Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

+config NET_RADIO
+ bool "Wireless LAN drivers (non-hamradio) & Wireless Extensions"
+ ---help---
+ Support for wireless LANs and everything having to do with radio,
+ but not with amateur radio or FM broadcasting.
+
+ Saying Y here also enables the Wireless Extensions (creates
+ /proc/net/wireless and enables iwconfig access). The Wireless
+ Extension is a generic API allowing a driver to expose to the user
+ space configuration and statistics specific to common Wireless LANs.
+ The beauty of it is that a single set of tool can support all the
+ variations of Wireless LANs, regardless of their type (as long as
+ the driver supports Wireless Extension). Another advantage is that
+ these parameters may be changed on the fly without restarting the
+ driver (or Linux). If you wish to use Wireless Extensions with
+ wireless PCMCIA (PC-) cards, you need to say Y here; you can fetch
+ the tools from
+ <http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html>.
+
+ Some user-level drivers for scarab devices which don't require
+ special kernel support are available from

+ tristate "STRIP (Metricom starmode radio IP)"
+ depends on NET_RADIO && INET
+ ---help---
+ Say Y if you have a Metricom radio and intend to use Starmode Radio
+ IP. STRIP is a radio protocol developed for the MosquitoNet project
+ (on the WWW at <http://mosquitonet.stanford.edu/>) to send Internet
+ traffic using Metricom radios. Metricom radios are small, battery
+ powered, 100kbit/sec packet radio transceivers, about the size and
+ weight of a cellular telephone. (You may also have heard them called
+ "Metricom modems" but we avoid the term "modem" because it misleads
+ many people into thinking that you can plug a Metricom modem into a
+ phone line and use it as a modem.)
+
+ You can use STRIP on any Linux machine with a serial port, although
+ it is obviously most useful for people with laptop computers. If you
+ think you might get a Metricom radio in the future, there is no harm
+ in saying Y to STRIP now, except that it makes the kernel a bit
+ bigger.

+ Aironet makes Arlan, a class of wireless LAN adapters. These use the
+ www.Telxon.com chip, which is also used on several similar cards.
+ This driver is tested on the 655 and IC2200 series cards. Look at
+ <http://www.ylenurme.ee/~elmer/655/> for the latest information.
+
+ The driver is built as two modules, arlan and arlan-proc. The latter
+ is the /proc interface and is not needed most of time.
+
+ On some computers the card ends up in non-valid state after some
+ time. Use a ping-reset script to clear it.

+ README
+ ------
+
+ This directory is mostly for Wireless LAN drivers, in their
+various incarnations (ISA, PCI, Pcmcia...).
+ This separate directory is needed because a lot of driver work
+on different bus (typically PCI + Pcmcia) and share 95% of the
+code. This allow the code and the config options to be in one single
+place instead of scattered all over the driver tree, which is never
+100% satisfactory.
+
+ Note : if you want more info on the topic of Wireless LANs,
+you are kindly invited to have a look at the Wireless Howto :
+ http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/
+ Some Wireless LAN drivers, like orinoco_cs, require the use of
+Wireless Tools to be configured :
+ http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Tools.html
+
+ Special notes for distribution maintainers :
+ 1) wvlan_cs will be discontinued soon in favor of orinoco_cs
+ 2) Please add Wireless Tools support in your scripts
+
+ Have fun...

+ *
+ * Filename: netwave_cs.c
+ * Version: 0.4.1
+ * Description: Netwave AirSurfer Wireless LAN PC Card driver
+ * Status: Experimental.
+ * Authors: John Markus Bjørndalen <johnm@cs.uit.no>
+ * Dag Brattli <dagb@cs.uit.no>
+ * David Hinds <dahinds@users.sourceforge.net>
+ * Created at: A long time ago!
+ * Modified at: Mon Nov 10 11:54:37 1997
+ * Modified by: Dag Brattli <dagb@cs.uit.no>
+ *
+ * Copyright (c) 1997 University of Tromsø, Norway
+ *
+ * Revision History:
+ *
+ * 08-Nov-97 15:14:47 John Markus Bjørndalen <johnm@cs.uit.no>
+ * - Fixed some bugs in netwave_rx and cleaned it up a bit.
+ * (One of the bugs would have destroyed packets when receiving
+ * multiple packets per interrupt).
+ * - Cleaned up parts of newave_hw_xmit.
+ * - A few general cleanups.
+ * 24-Oct-97 13:17:36 Dag Brattli <dagb@cs.uit.no>
+ * - Fixed netwave_rx receive function (got updated docs)
+ * Others:
+ * - Changed name from xircnw to netwave, take a look at
+ * http://www.netwave-wireless.com
+ * - Some reorganizing of the code
+ * - Removed possible race condition between interrupt handler and transmit
+ * function
+ * - Started to add wireless extensions, but still needs some coding
+ * - Added watchdog for better handling of transmission timeouts
+ * (hopefully this works better)

+ *
+ * v0.06b -> v0.06c - 29/5/2001 - Jean II

+ * o Removed bogus message on CRC error.
+ * o Merged fixes for v0.08 Prism 2 firmware from William Waghorn
+ * <willwaghorn AT yahoo.co.uk>
+ * o Slight cleanup/re-arrangement of firmware detection code.
+ *
+ * v0.06d -> v0.06e - 1/8/2001 - David Gibson
+ * o Removed some redundant global initializers (orinoco_cs.c).
+ * o Added some module metadata
+ *
+ * v0.06e -> v0.06f - 14/8/2001 - David Gibson
+ * o Wording fix to license
+ * o Added a 'use_alternate_encaps' module parameter for APs which need an
+ * oui of 00:00:00. We really need a better way of handling this, but
+ * the module flag is better than nothing for now.
+ *
+ * v0.06f -> v0.07 - 20/8/2001 - David Gibson
+ * o Removed BAP error retries from hermes_bap_seek(). For Tx we now
+ * let the upper layers handle the retry, we retry explicitly in the
+ * Rx path, but don't make as much noise about it.
+ * o Firmware detection cleanups.
+ *
+ * v0.07 -> v0.07a - 1/10/3001 - Jean II
+ * o Add code to read Symbol firmware revision, inspired by latest code
+ * in Spectrum24 by Lee John Keyser-Allen - Thanks Lee !
+ * o Thanks to Jared Valentine <hidden AT xmission.com> for "providing" me
+ * a 3Com card with a recent firmware, fill out Symbol firmware
+ * capabilities of latest rev (2.20), as well as older Symbol cards.
+ * o Disable Power Management in newer Symbol firmware, the API
+ * has changed (documentation needed).
+ *
+ * v0.07a -> v0.08 - 3/10/2001 - David Gibson
+ * o Fixed a possible buffer overrun found by the Stanford checker (in
+ * dldwd_ioctl_setiwencode()). Can only be called by root anyway, so not
+ * a big problem.
+ * o Turned has_big_wep on for Intersil cards. That's not true for all of
+ * them but we should at least let the capable ones try.
+ * o Wait for BUSY to clear at the beginning of hermes_bap_seek(). I
+ * realized that my assumption that the driver's serialization
+ * would prevent the BAP being busy on entry was possibly false, because
+ * things other than seeks may make the BAP busy.
+ * o Use "alternate" (oui 00:00:00) encapsulation by default.
+ * Setting use_old_encaps will mimic the old behaviour, but I think we
+ * will be able to eliminate this.
+ * o Don't try to make __initdata const (the version string). This can't
+ * work because of the way the __initdata sectioning works.
+ * o Added MODULE_LICENSE tags.
+ * o Support for PLX (transparent PCMCIA->PCI bridge) cards.
+ * o Changed to using the new type-fascist min/max.
+ *
+ * v0.08 -> v0.08a - 9/10/2001 - David Gibson
+ * o Inserted some missing acknowledgements/info into the Changelog.
+ * o Fixed some bugs in the normalization of signal level reporting.
+ * o Fixed bad bug in WEP key handling on Intersil and Symbol firmware,
+ * which led to an instant crash on big-endian machines.
+ *
+ * v0.08a -> v0.08b - 20/11/2001 - David Gibson
+ * o Lots of cleanup and bugfixes in orinoco_plx.c
+ * o Cleanup to handling of Tx rate setting.
+ * o Removed support for old encapsulation method.
+ * o Removed old "dldwd" names.
+ * o Split RID constants into a new file hermes_rid.h
+ * o Renamed RID constants to match linux-wlan-ng and prism2.o
+ * o Bugfixes in hermes.c
+ * o Poke the PLX's INTCSR register, so it actually starts
+ * generating interrupts. These cards might actually work now.
+ * o Update to wireless extensions v12 (Jean II)
+ * o Support for tallies and inquire command (Jean II)
+ * o Airport updates for newer PPC kernels (BenH)
+ *
+ * v0.08b -> v0.09 - 21/12/2001 - David Gibson
+ * o Some new PCI IDs for PLX cards.
+ * o Removed broken attempt to do ALLMULTI reception. Just use
+ * promiscuous mode instead
+ * o Preliminary work for list-AP (Jean II)
+ * o Airport updates from (BenH)
+ * o Eliminated racy hw_ready stuff
+ * o Fixed generation of fake events in irq handler. This should
+ * finally kill the EIO problems (Jean II & dgibson)
+ * o Fixed breakage of bitrate set/get on Agere firmware (Jean II)
+ *
+ * v0.09 -> v0.09a - 2/1/2002 - David Gibson
+ * o Fixed stupid mistake in multicast list handling, triggering
+ * a BUG()
+ *
+ * v0.09a -> v0.09b - 16/1/2002 - David Gibson
+ * o Fixed even stupider mistake in new interrupt handling, which
+ * seriously broke things on big-endian machines.
+ * o Removed a bunch of redundant includes and exports.
+ * o Removed a redundant MOD_{INC,DEC}_USE_COUNT pair in airport.c
+ * o Don't attempt to do hardware level multicast reception on
+ * Intersil firmware, just go promisc instead.
+ * o Typo fixed in hermes_issue_cmd()
+ * o Eliminated WIRELESS_SPY #ifdefs
+ * o Status code reported on Tx exceptions
+ * o Moved netif_wake_queue() from ALLOC interrupts to TX and TXEXC
+ * interrupts, which should fix the timeouts we're seeing.
+ *
+ * v0.09b -> v0.10 - 25 Feb 2002 - David Gibson
+ * o Removed nested structures used for header parsing, so the
+ * driver should now work without hackery on ARM
+ * o Fix for WEP handling on Intersil (Hawk Newton)
+ * o Eliminated the /proc/hermes/ethXX/regs debugging file. It
+ * was never very useful.
+ * o Make Rx errors less noisy.
+ *
+ * v0.10 -> v0.11 - 5 Apr 2002 - David Gibson
+ * o Laid the groundwork in hermes.[ch] for devices which map
+ * into PCI memory space rather than IO space.
+ * o Fixed bug in multicast handling (cleared multicast list when
+ * leaving promiscuous mode).
+ * o Relegated Tx error messages to debug.
+ * o Cleaned up / corrected handling of allocation lengths.
+ * o Set OWNSSID in IBSS mode for WinXP interoperability (jimc).
+ * o Change to using alloc_etherdev() for structure allocations.
+ * o Check for and drop undersized packets.
+ * o Fixed a race in stopping/waking the queue. This should fix
+ * the timeout problems (Pavel Roskin)
+ * o Reverted to netif_wake_queue() on the ALLOC event.
+ * o Fixes for recent Symbol firmwares which lack AP density
+ * (Pavel Roskin).
+ *
+ * v0.11 -> v0.11a - 29 Apr 2002 - David Gibson
+ * o Handle different register spacing, necessary for Prism 2.5
+ * PCI adaptors (Steve Hill).
+ * o Cleaned up initialization of card structures in orinoco_cs
+ * and airport. Removed card->priv field.
+ * o Make response structure optional for hermes_docmd_wait()
+ * Pavel Roskin)
+ * o Added PCI id for Nortel emobility to orinoco_plx.c.
+ * o Cleanup to handling of Symbol's allocation bug. (Pavel Roskin)
+ * o Cleanups to firmware capability detection.
+ * o Arrange for orinoco_pci.c to override firmware detection.
+ * We should be able to support the PCI Intersil cards now.
+ * o Cleanup handling of reset_cor and hard_reset (Pavel Roskin).
+ * o Remove erroneous use of USER_BAP in the TxExc handler (Jouni
+ * Malinen).
+ * o Makefile changes for better integration into David Hinds
+ * pcmcia-cs package.
+ *
+ * v0.11a -> v0.11b - 1 May 2002 - David Gibson
+ * o Better error reporting in orinoco_plx_init_one()
+ * o Fixed multiple bad kfree() bugs introduced by the
+ * alloc_orinocodev() changes.
+ *
+ * v0.11b -> v0.12 - 19 Jun 2002 - David Gibson
+ * o Support changing the MAC address.
+ * o Correct display of Intersil firmware revision numbers.
+ * o Entirely revised locking scheme. Should be both simpler and
+ * better.
+ * o Merged some common code in orinoco_plx, orinoco_pci and
+ * airport by creating orinoco_default_{open,stop,reset}()
+ * which are used as the dev->open, dev->stop, priv->reset
+ * callbacks if none are specified when alloc_orinocodev() is
+ * called.
+ * o Removed orinoco_plx_interrupt() and orinoco_pci_interrupt().
+ * They didn't do anything.
+ *
+ * v0.12 -> v0.12a - 4 Jul 2002 - David Gibson
+ * o Some rearrangement of code.
+ * o Numerous fixups to locking and rest handling, particularly
+ * for PCMCIA.
+ * o This allows open and stop net_device methods to be in
+ * orinoco.c now, rather than in the init modules.
+ * o In orinoco_cs.c link->priv now points to the struct
+ * net_device not to the struct orinoco_private.
+ * o Added a check for undersized SNAP frames, which could cause
+ * crashes.
+ *
+ * v0.12a -> v0.12b - 11 Jul 2002 - David Gibson
+ * o Fix hw->num_init testing code, so num_init is actually
+ * incremented.
+ * o Fix very stupid bug in orinoco_cs which broke compile with
+ * CONFIG_SMP.
+ * o Squashed a warning.
+ *
+ * v0.12b -> v0.12c - 26 Jul 2002 - David Gibson
+ * o Change to C9X style designated initializers.
+ * o Add support for 3Com AirConnect PCI.
+ * o No longer ignore the hard_reset argument to
+ * alloc_orinocodev(). Oops.
+ *
+ * v0.12c -> v0.13beta1 - 13 Sep 2002 - David Gibson
+ * o Revert the broken 0.12* locking scheme and go to a new yet
+ * simpler scheme.
+ * o Do firmware resets only in orinoco_init() and when waking
+ * the card from hard sleep.
+ *
+ * v0.13beta1 -> v0.13 - 27 Sep 2002 - David Gibson
+ * o Re-introduced full resets (via schedule_task()) on Tx
+ * timeout.
+ *
+ * v0.13 -> v0.13a - 30 Sep 2002 - David Gibson
+ * o Minor cleanups to info frame handling. Add basic support
+ * for linkstatus info frames.
+ * o Include required kernel headers in orinoco.h, to avoid
+ * compile problems.
+ *
+ * v0.13a -> v0.13b - 10 Feb 2003 - David Gibson
+ * o Implemented hard reset for Airport cards
+ * o Experimental suspend/resume implementation for orinoco_pci
+ * o Abolished /proc debugging support, replaced with a debugging
+ * iwpriv. Now it's ugly and simple instead of ugly and complex.
+ * o Bugfix in hermes.c if the firmware returned a record length
+ * of 0, we could go clobbering memory.
+ * o Bugfix in orinoco_stop() - it used to fail if hw_unavailable
+ * was set, which was usually true on PCMCIA hot removes.
+ * o Track LINKSTATUS messages, silently drop Tx packets before
+ * we are connected (avoids confusing the firmware), and only
+ * give LINKSTATUS printk()s if the status has changed.
+ *
+ * v0.13b -> v0.13c - 11 Mar 2003 - David Gibson
+ * o Cleanup: use dev instead of priv in various places.
+ * o Bug fix: Don't ReleaseConfiguration on RESET_PHYSICAL event
+ * if we're in the middle of a (driver initiated) hard reset.
+ * o Bug fix: ETH_ZLEN is supposed to include the header
+ * (Dionysus Blazakis & Manish Karir)
+ * o Convert to using workqueues instead of taskqueues (and
+ * backwards compatibility macros for pre 2.5.41 kernels).
+ * o Drop redundant (I think...) MOD_{INC,DEC}_USE_COUNT in
+ * airport.c
+ * o New orinoco_tmd.c init module from Joerg Dorchain for
+ * TMD7160 based PCI to PCMCIA bridges (similar to
+ * orinoco_plx.c).
+ *
+ * v0.13c -> v0.13d - 22 Apr 2003 - David Gibson
+ * o Make hw_unavailable a counter, rather than just a flag, this
+ * is necessary to avoid some races (such as a card being
+ * removed in the middle of orinoco_reset().
+ * o Restore Release/RequestConfiguration in the PCMCIA event handler
+ * when dealing with a driver initiated hard reset. This is
+ * necessary to prevent hangs due to a spurious interrupt while
+ * the reset is in progress.
+ * o Clear the 802.11 header when transmitting, even though we
+ * don't use it. This fixes a long standing bug on some
+ * firmwares, which seem to get confused if that isn't done.
+ * o Be less eager to de-encapsulate SNAP frames, only do so if
+ * the OUI is 00:00:00 or 00:00:f8, leave others alone. The old
+ * behaviour broke CDP (Cisco Discovery Protocol).
+ * o Use dev instead of priv for free_irq() as well as
+ * request_irq() (oops).
+ * o Attempt to reset rather than giving up if we get too many
+ * IRQs.
+ * o Changed semantics of __orinoco_down() so it can be called
+ * safely with hw_unavailable set. It also now clears the
+ * linkstatus (since we're going to have to reassociate).
+ *
+ * v0.13d -> v0.13e - 12 May 2003 - David Gibson
+ * o Support for post-2.5.68 return values from irq handler.
+ * o Fixed bug where underlength packets would be double counted
+ * in the rx_dropped statistics.
+ * o Provided a module parameter to suppress linkstatus messages.
+ *
+ * v0.13e -> v0.14alpha1 - 30 Sep 2003 - David Gibson
+ * o Replaced priv->connected logic with netif_carrier_on/off()
+ * calls.
+ * o Remove has_ibss_any and never set the CREATEIBSS RID when
+ * the ESSID is empty. Too many firmwares break if we do.
+ * o 2.6 merges: Replace pdev->slot_name with pci_name(), remove
+ * __devinitdata from PCI ID tables, use free_netdev().
+ * o Enabled shared-key authentication for Agere firmware (from
+ * Robert J. Moore <Robert.J.Moore AT allanbank.com>
+ * o Move netif_wake_queue() (back) to the Tx completion from the
+ * ALLOC event. This seems to prevent/mitigate the rolling
+ * error -110 problems at least on some Intersil firmwares.
+ * Theoretically reduces performance, but I can't measure it.
+ * Patch from Andrew Tridgell <tridge AT samba.org>
+ *
+ * v0.14alpha1 -> v0.14alpha2 - 20 Oct 2003 - David Gibson
+ * o Correctly turn off shared-key authentication when requested
+ * (bugfix from Robert J. Moore).
+ * o Correct airport sleep interfaces for current 2.6 kernels.
+ * o Add code for key change without disabling/enabling the MAC
+ * port. This is supposed to allow 802.1x to work sanely, but
+ * doesn't seem to yet.
+ *
+ * TODO
+ * o New wireless extensions API (patch from Moustafa
+ * Youssef, updated by Jim Carter and Pavel Roskin).
+ * o Handle de-encapsulation within network layer, provide 802.11
+ * headers (patch from Thomas 'Dent' Mirlacher)
+ * o RF monitor mode support
+ * o Fix possible races in SPY handling.
+ * o Disconnect wireless extensions from fundamental configuration.
+ * o (maybe) Software WEP support (patch from Stano Meduna).
+ * o (maybe) Use multiple Tx buffers - driver handling queue
+ * rather than firmware.

+/* Locking and synchronization:
+ *
+ * The basic principle is that everything is serialized through a
+ * single spinlock, priv->lock. The lock is used in user, bh and irq
+ * context, so when taken outside hardirq context it should always be
+ * taken with interrupts disabled. The lock protects both the
+ * hardware and the struct orinoco_private.
+ *
+ * Another flag, priv->hw_unavailable indicates that the hardware is
+ * unavailable for an extended period of time (e.g. suspended, or in
+ * the middle of a hard reset). This flag is protected by the
+ * spinlock. All code which touches the hardware should check the
+ * flag after taking the lock, and if it is set, give up on whatever
+ * they are doing and drop the lock again. The orinoco_lock()
+ * function handles this (it unlocks and returns -EBUSY if
+ * hw_unavailable is non-zero).

+/*
+ * Theory of operation...
+ * -------------------
+ * Maybe you had a look in orinoco_plx. Well, this is totally different...
+ *
+ * The card contains only one PCI region, which contains all the usual
+ * hermes registers.
+ *
+ * The driver will memory map this region in normal memory. Because
+ * the hermes registers are mapped in normal memory and not in ISA I/O
+ * post space, we can't use the usual inw/outw macros and we need to
+ * use readw/writew.
+ * This slight difference force us to compile our own version of
+ * hermes.c with the register access macro changed. That's a bit
+ * hackish but works fine.
+ *
+ * Note that the PCI region is pretty big (4K). That's much more than
+ * the usual set of hermes register (0x0 -> 0x3E). I've got a strong
+ * suspicion that the whole memory space of the adapter is in fact in
+ * this region. Accessing directly the adapter memory instead of going
+ * through the usual register would speed up significantely the
+ * operations...
+ *
+ * Finally, the card looks like this :
+-----------------------
+ Bus 0, device 14, function 0:
+ Network controller: PCI device 1260:3873 (Harris Semiconductor) (rev 1).
+ IRQ 11.
+ Master Capable. Latency=248.

+ * card we don't have the PCI id for, and looks like it should work,
+ * drop me mail with the id and "it works"/"it doesn't work".
+ *
+ * Note: if everything gets detected fine but it doesn't actually send
+ * or receive packets, your first port of call should probably be to
+ * try newer firmware in the card. Especially if you're doing Ad-Hoc
+ * modes.
+ *
+ * The actual driving is done by orinoco.c, this is just resource
+ * allocation stuff. The explanation below is courtesy of Ryan Niemi
+ * on the linux-wlan-ng list at
+ * http://archives.neohapsis.com/archives/dev/linux-wlan/2001-q1/0026.html
+ *
+ * The PLX9052-based cards (WL11000 and several others) are a
+ * different beast than the usual PCMCIA-based PRISM2 configuration
+ * expected by wlan-ng. Here's the general details on how the WL11000
+ * PCI adapter works:
+ *
+ * - Two PCI I/O address spaces, one 0x80 long which contains the
+ * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA
+ * slot I/O address space.
+ *
+ * - One PCI memory address space, mapped to the PCMCIA memory space
+ * (containing the CIS).
+ *
+ * After identifying the I/O and memory space, you can read through
+ * the memory space to confirm the CIS's device ID or manufacturer ID
+ * to make sure it's the expected card. qKeep in mind that the PCMCIA
+ * spec specifies the CIS as the lower 8 bits of each word read from
+ * the CIS, so to read the bytes of the CIS, read every other byte
+ * (0,2,4,...). Passing that test, you need to enable the I/O address
+ * space on the PCMCIA card via the PCMCIA COR register. This is the
+ * first byte following the CIS. In my case (which may not have any
+ * relation to what's on the PRISM2 cards), COR was at offset 0x800
+ * within the PCI memory space. Write 0x41 to the COR register to
+ * enable I/O mode and to select level triggered interrupts. To
+ * confirm you actually succeeded, read the COR register back and make
+ * sure it actually got set to 0x41, incase you have an unexpected
+ * card inserted.
+ *
+ * Following that, you can treat the second PCI I/O address space (the
+ * one that's not 0x80 in length) as the PCMCIA I/O space.
+ *
+ * Note that in the Eumitcom's source for their drivers, they register
+ * the interrupt as edge triggered when registering it with the
+ * Windows kernel. I don't recall how to register edge triggered on
+ * Linux (if it can be done at all). But in some experimentation, I
+ * don't see much operational difference between using either
+ * interrupt mode. Don't mess with the interrupt mode in the COR
+ * register though, as the PLX9052 wants level triggers with the way
+ * the serial EEPROM configures it on the WL11000.
+ *
+ * There's some other little quirks related to timing that I bumped
+ * into, but I don't recall right now. Also, there's two variants of
+ * the WL11000 I've seen, revision A1 and T2. These seem to differ
+ * slightly in the timings configured in the wait-state generator in
+ * the PLX9052. There have also been some comments from Eumitcom that
+ * cards shouldn't be hot swapped, apparently due to risk of cooking
+ * the PLX9052. I'm unsure why they believe this, as I can't see
+ * anything in the design that would really cause a problem, except
+ * for crashing drivers not written to expect it. And having developed
+ * drivers for the WL11000, I'd say it's quite tricky to write code
+ * that will successfully deal with a hot unplug. Very odd things
+ * happen on the I/O side of things. But anyway, be warned. Despite
+ * that, I've hot-swapped a number of times during debugging and
+ * driver development for various reasons (stuck WAIT# line after the
+ * radio card's firmware locks up).
+ *
+ * Hope this is enough info for someone to add PLX9052 support to the
+ * wlan-ng card. In the case of the WL11000, the PCI ID's are
+ * 0x1639/0x0200, with matching subsystem ID's. Other PLX9052-based
+ * manufacturers other than Eumitcom (or on cards other than the
+ * WL11000) may have different PCI ID's.
+ *
+ * If anyone needs any more specific info, let me know. I haven't had
+ * time to implement support myself yet, and with the way things are
+ * going, might not have time for a while..

+ *
+ * The actual driving is done by orinoco.c, this is just resource
+ * allocation stuff.
+ *
+ * This driver is modeled after the orinoco_plx driver. The main
+ * difference is that the TMD chip has only IO port ranges and no
+ * memory space, i.e. no access to the CIS. Compared to the PLX chip,
+ * the io range functionalities are exchanged.

+ * strip.c This module implements Starmode Radio IP (STRIP)
+ * for kernel-based devices like TTY. It interfaces between a
+ * raw TTY, and the kernel's INET protocol layers (via DDI).
+ *
+ * Version: @(#)strip.c 1.3 July 1997
+ *
+ * Author: Stuart Cheshire <cheshire@cs.stanford.edu>
+ *
+ * Fixes: v0.9 12th Feb 1996 (SC)
+ * New byte stuffing (2+6 run-length encoding)
+ * New watchdog timer task
+ * New Protocol key (SIP0)
+ *
+ * v0.9.1 3rd March 1996 (SC)
+ * Changed to dynamic device allocation -- no more compile
+ * time (or boot time) limit on the number of STRIP devices.
+ *
+ * v0.9.2 13th March 1996 (SC)
+ * Uses arp cache lookups (but doesn't send arp packets yet)
+ *
+ * v0.9.3 17th April 1996 (SC)
+ * Fixed bug where STR_ERROR flag was getting set unneccessarily
+ * (causing otherwise good packets to be unneccessarily dropped)
+ *
+ * v0.9.4 27th April 1996 (SC)
+ * First attempt at using "&COMMAND" Starmode AT commands
+ *
+ * v0.9.5 29th May 1996 (SC)
+ * First attempt at sending (unicast) ARP packets
+ *
+ * v0.9.6 5th June 1996 (Elliot)
+ * Put "message level" tags in every "printk" statement
+ *
+ * v0.9.7 13th June 1996 (laik)
+ * Added support for the /proc fs
+ *
+ * v0.9.8 July 1996 (Mema)
+ * Added packet logging
+ *
+ * v1.0 November 1996 (SC)
+ * Fixed (severe) memory leaks in the /proc fs code
+ * Fixed race conditions in the logging code
+ *
+ * v1.1 January 1997 (SC)
+ * Deleted packet logging (use tcpdump instead)
+ * Added support for Metricom Firmware v204 features
+ * (like message checksums)
+ *
+ * v1.2 January 1997 (SC)
+ * Put portables list back in
+ *
+ * v1.3 July 1997 (SC)
+ * Made STRIP driver set the radio's baud rate automatically.
+ * It is no longer necessarily to manually set the radio's
+ * rate permanently to 115200 -- the driver handles setting
+ * the rate automatically.

+ * Note: manual_dev_addr hack
+ *
+ * It is not possible to change the hardware address of a Metricom radio,
+ * or to send packets with a user-specified hardware source address, thus
+ * trying to manually set a hardware source address is a questionable
+ * thing to do. However, if the user *does* manually set the hardware
+ * source address of a STRIP interface, then the kernel will believe it,
+ * and use it in certain places. For example, the hardware address listed
+ * by ifconfig will be the manual address, not the true one.
+ * (Both addresses are listed in /proc/net/strip.)
+ * Also, ARP packets will be sent out giving the user-specified address as
+ * the source address, not the real address. This is dangerous, because
+ * it means you won't receive any replies -- the ARP replies will go to
+ * the specified address, which will be some other radio. The case where
+ * this is useful is when that other radio is also connected to the same
+ * machine. This allows you to connect a pair of radios to one machine,
+ * and to use one exclusively for inbound traffic, and the other
+ * exclusively for outbound traffic. Pretty neat, huh?
+ *
+ * Here's the full procedure to set this up:
+ *
+ * 1. "slattach" two interfaces, e.g. st0 for outgoing packets,
+ * and st1 for incoming packets
+ *
+ * 2. "ifconfig" st0 (outbound radio) to have the hardware address
+ * which is the real hardware address of st1 (inbound radio).
+ * Now when it sends out packets, it will masquerade as st1, and
+ * replies will be sent to that radio, which is exactly what we want.
+ *
+ * 3. Set the route table entry ("route add default ..." or
+ * "route add -net ...", as appropriate) to send packets via the st0
+ * interface (outbound radio). Do not add any route which sends packets
+ * out via the st1 interface -- that radio is for inbound traffic only.
+ *
+ * 4. "ifconfig" st1 (inbound radio) to have hardware address zero.
+ * This tells the STRIP driver to "shut down" that interface and not
+ * send any packets through it. In particular, it stops sending the
+ * periodic gratuitous ARP packets that a STRIP interface normally sends.
+ * Also, when packets arrive on that interface, it will search the
+ * interface list to see if there is another interface who's manual
+ * hardware address matches its own real address (i.e. st0 in this
+ * example) and if so it will transfer ownership of the skbuff to
+ * that interface, so that it looks to the kernel as if the packet
+ * arrived on that interface. This is necessary because when the
+ * kernel sends an ARP packet on st0, it expects to get a reply on
+ * st0, and if it sees the reply come from st1 then it will ignore
+ * it (to be accurate, it puts the entry in the ARP table, but
+ * labelled in such a way that st0 can't use it).
+ *
+ * Thanks to Petros Maniatis for coming up with the idea of splitting
+ * inbound and outbound traffic between two interfaces, which turned
+ * out to be really easy to implement, even if it is a bit of a hack.
+ *
+ * Having set a manual address on an interface, you can restore it
+ * to automatic operation (where the address is automatically kept
+ * consistent with the real address of the radio) by setting a manual
+ * address of all ones, e.g. "ifconfig st0 hw strip FFFFFFFFFFFF"
+ * This 'turns off' manual override mode for the device address.
+ *
+ * Note: The IEEE 802 headers reported in tcpdump will show the *real*
+ * radio addresses the packets were sent and received from, so that you
+ * can see what is really going on with packets, and which interfaces
+ * they are really going through.

+/*
+ * This driver provides a Linux interface to the WaveLAN ISA hardware.
+ * The WaveLAN is a product of Lucent (http://www.wavelan.com/).
+ * This division was formerly part of NCR and then AT&T.
+ * WaveLANs are also distributed by DEC (RoamAbout DS) and Digital Ocean.
+ *
+ * To learn how to use this driver, read the NET3 HOWTO.
+ * If you want to exploit the many other functionalities, read the comments
+ * in the code.
+ *
+ * This driver is the result of the effort of many people (see below).
+ */
+
+/* ------------------------ SPECIFIC NOTES ------------------------ */
+/*
+ * Web page
+ * --------
+ * I try to maintain a web page with the Wireless LAN Howto at :
+ * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
+ *
+ * SMP
+ * ---
+ * We now are SMP compliant (I eventually fixed the remaining bugs).
+ * The driver has been tested on a dual P6-150 and survived my usual
+ * set of torture tests.
+ * Anyway, I spent enough time chasing interrupt re-entrancy during
+ * errors or reconfigure, and I designed the locked/unlocked sections
+ * of the driver with great care, and with the recent addition of
+ * the spinlock (thanks to the new API), we should be quite close to
+ * the truth.
+ * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
+ * but better safe than sorry (especially at 2 Mb/s ;-).
+ *
+ * I have also looked into disabling only our interrupt on the card
+ * (via HACR) instead of all interrupts in the processor (via cli),
+ * so that other driver are not impacted, and it look like it's
+ * possible, but it's very tricky to do right (full of races). As
+ * the gain would be mostly for SMP systems, it can wait...
+ *
+ * Debugging and options
+ * ---------------------
+ * You will find below a set of '#define" allowing a very fine control
+ * on the driver behaviour and the debug messages printed.
+ * The main options are :
+ * o SET_PSA_CRC, to have your card correctly recognised by
+ * an access point and the Point-to-Point diagnostic tool.
+ * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
+ * (otherwise we always start afresh with some defaults)
+ *
+ * wavelan.o is too darned big
+ * ---------------------------
+ * That's true! There is a very simple way to reduce the driver
+ * object by 33%! Comment out the following line:
+ * #include <linux/wireless.h>
+ * Other compile options can also reduce the size of it...
+ *
+ * MAC address and hardware detection:
+ * -----------------------------------
+ * The detection code for the WaveLAN checks that the first three
+ * octets of the MAC address fit the company code. This type of
+ * detection works well for AT&T cards (because the AT&T code is
+ * hardcoded in wavelan.h), but of course will fail for other
+ * manufacturers.
+ *
+ * If you are sure that your card is derived from the WaveLAN,
+ * here is the way to configure it:
+ * 1) Get your MAC address
+ * a) With your card utilities (wfreqsel, instconf, etc.)
+ * b) With the driver:
+ * o compile the kernel with DEBUG_CONFIG_INFO enabled
+ * o Boot and look the card messages
+ * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan.h)
+ * 3) Compile and verify
+ * 4) Send me the MAC code. I will include it in the next version.
+ *
+ */
+
+/* --------------------- WIRELESS EXTENSIONS --------------------- */
+/*
+ * This driver is the first to support "wireless extensions".
+ * This set of extensions provides a standard way to control the wireless
+ * characteristics of the hardware. Applications such as mobile IP may
+ * take advantage of it.
+ *
+ * You will need to enable the CONFIG_NET_RADIO define in the kernel
+ * configuration to enable the wireless extensions (this is the one
+ * giving access to the radio network device choice).
+ *
+ * It might also be a good idea as well to fetch the wireless tools to
+ * configure the device and play a bit.

+/* --------------------------- HISTORY --------------------------- */
+/*
+ * This is based on information in the drivers' headers. It may not be
+ * accurate, and I guarantee only my best effort.
+ *
+ * The history of the WaveLAN drivers is as complicated as the history of
+ * the WaveLAN itself (NCR -> AT&T -> Lucent).
+ *
+ * It all started with Anders Klemets <klemets@paul.rutgers.edu>
+ * writing a WaveLAN ISA driver for the Mach microkernel. Girish
+ * Welling <welling@paul.rutgers.edu> had also worked on it.
+ * Keith Moore modified this for the PCMCIA hardware.
+ *
+ * Robert Morris <rtm@das.harvard.edu> ported these two drivers to BSDI
+ * and added specific PCMCIA support (there is currently no equivalent
+ * of the PCMCIA package under BSD).
+ *
+ * Jim Binkley <jrb@cs.pdx.edu> ported both BSDI drivers to FreeBSD.
+ *
+ * Bruce Janson <bruce@cs.usyd.edu.au> ported the BSDI ISA driver to Linux.
+ *
+ * Anthony D. Joseph <adj@lcs.mit.edu> started to modify Bruce's driver
+ * (with help of the BSDI PCMCIA driver) for PCMCIA.
+ * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished this work.
+ * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
+ * 2.00 cards correctly (2.4 GHz with frequency selection).
+ * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
+ * PCMCIA package (and bug corrections).
+ *
+ * I (Jean Tourrilhes - jt@hplb.hpl.hp.com) then started to make some
+ * patches to the PCMCIA driver. Later, I added code in the ISA driver
+ * for Wireless Extensions and full support of frequency selection
+ * cards. Then, I did the same to the PCMCIA driver, and did some
+ * reorganisation. Finally, I came back to the ISA driver to
+ * upgrade it at the same level as the PCMCIA one and reorganise
+ * the code.
+ * Loeke Brederveld <lbrederv@wavelan.com> from Lucent has given me
+ * much needed information on the WaveLAN hardware.

+/* ------------------------- IMPROVEMENTS ------------------------- */
+/*
+ * I proudly present:
+ *
+ * Changes made in first pre-release:
+ * ----------------------------------
+ * - reorganisation of the code, function name change
+ * - creation of private header (wavelan.p.h)
+ * - reorganised debug messages
+ * - more comments, history, etc.
+ * - mmc_init: configure the PSA if not done
+ * - mmc_init: correct default value of level threshold for PCMCIA
+ * - mmc_init: 2.00 detection better code for 2.00 initialization
+ * - better info at startup
+ * - IRQ setting (note: this setting is permanent)
+ * - watchdog: change strategy (and solve module removal problems)
+ * - add wireless extensions (ioctl and get_wireless_stats)
+ * get/set nwid/frequency on fly, info for /proc/net/wireless
+ * - more wireless extensions: SETSPY and GETSPY
+ * - make wireless extensions optional
+ * - private ioctl to set/get quality and level threshold, histogram
+ * - remove /proc/net/wavelan
+ * - suppress useless stuff from lp (net_local)
+ * - kernel 2.1 support (copy_to/from_user instead of memcpy_to/fromfs)
+ * - add message level (debug stuff in /var/adm/debug and errors not
+ * displayed at console and still in /var/adm/messages)
+ * - multi device support
+ * - start fixing the probe (init code)
+ * - more inlines
+ * - man page
+ * - many other minor details and cleanups
+ *
+ * Changes made in second pre-release:
+ * -----------------------------------
+ * - clean up init code (probe and module init)
+ * - better multiple device support (module)
+ * - name assignment (module)
+ *
+ * Changes made in third pre-release:
+ * ----------------------------------
+ * - be more conservative on timers
+ * - preliminary support for multicast (I still lack some details)
+ *
+ * Changes made in fourth pre-release:
+ * -----------------------------------
+ * - multicast (revisited and finished)
+ * - avoid reset in set_multicast_list (a really big hack)
+ * if somebody could apply this code for other i82586 based drivers
+ * - share onboard memory 75% RU and 25% CU (instead of 50/50)
+ *
+ * Changes made for release in 2.1.15:
+ * -----------------------------------
+ * - change the detection code for multi manufacturer code support
+ *
+ * Changes made for release in 2.1.17:
+ * -----------------------------------
+ * - update to wireless extensions changes
+ * - silly bug in card initial configuration (psa_conf_status)
+ *
+ * Changes made for release in 2.1.27 & 2.0.30:
+ * --------------------------------------------
+ * - small bug in debug code (probably not the last one...)
+ * - remove extern keyword for wavelan_probe()
+ * - level threshold is now a standard wireless extension (version 4 !)
+ * - modules parameters types (new module interface)
+ *
+ * Changes made for release in 2.1.36:
+ * -----------------------------------
+ * - byte count stats (courtesy of David Hinds)
+ * - remove dev_tint stuff (courtesy of David Hinds)
+ * - encryption setting from Brent Elphick (thanks a lot!)
+ * - 'ioaddr' to 'u_long' for the Alpha (thanks to Stanislav Sinyagin)
+ *
+ * Other changes (not by me) :
+ * -------------------------
+ * - Spelling and gramar "rectification".
+ *
+ * Changes made for release in 2.0.37 & 2.2.2 :
+ * ------------------------------------------
+ * - Correct status in /proc/net/wireless
+ * - Set PSA CRC to make PtP diagnostic tool happy (Bob Gray)
+ * - Module init code don't fail if we found at least one card in
+ * the address list (Karlis Peisenieks)
+ * - Missing parenthesis (Christopher Peterson)
+ * - Correct i82586 configuration parameters
+ * - Encryption initialisation bug (Robert McCormack)
+ * - New mac addresses detected in the probe
+ * - Increase watchdog for busy environments
+ *
+ * Changes made for release in 2.0.38 & 2.2.7 :
+ * ------------------------------------------
+ * - Correct the reception logic to better report errors and avoid
+ * sending bogus packet up the stack
+ * - Delay RU config to avoid corrupting first received packet
+ * - Change config completion code (to actually check something)
+ * - Avoid reading out of bound in skbuf to transmit
+ * - Rectify a lot of (useless) debugging code
+ * - Change the way to `#ifdef SET_PSA_CRC'
+ *
+ * Changes made for release in 2.2.11 & 2.3.13 :
+ * -------------------------------------------
+ * - Change e-mail and web page addresses
+ * - Watchdog timer is now correctly expressed in HZ, not in jiffies
+ * - Add channel number to the list of frequencies in range
+ * - Add the (short) list of bit-rates in range
+ * - Developp a new sensitivity... (sens.value & sens.fixed)
+ *
+ * Changes made for release in 2.2.14 & 2.3.23 :
+ * -------------------------------------------
+ * - Fix check for root permission (break instead of exit)
+ * - New nwid & encoding setting (Wireless Extension 9)
+ *
+ * Changes made for release in 2.3.49 :
+ * ----------------------------------
+ * - Indentation reformating (Alan)
+ * - Update to new network API (softnet - 2.3.43) :
+ * o replace dev->tbusy (Alan)
+ * o replace dev->tstart (Alan)
+ * o remove dev->interrupt (Alan)
+ * o add SMP locking via spinlock in splxx (me)
+ * o add spinlock in interrupt handler (me)
+ * o use kernel watchdog instead of ours (me)
+ * o increase watchdog timeout (kernel is more sensitive) (me)
+ * o verify that all the changes make sense and work (me)
+ * - Fixup a potential gotcha when reconfiguring and thighten a bit
+ * the interactions with Tx queue.
+ *
+ * Changes made for release in 2.4.0 :
+ * ---------------------------------
+ * - Fix spinlock stupid bugs that I left in. The driver is now SMP
+ * compliant and doesn't lockup at startup.
+ *
+ * Changes made for release in 2.5.2 :
+ * ---------------------------------
+ * - Use new driver API for Wireless Extensions :
+ * o got rid of wavelan_ioctl()
+ * o use a bunch of iw_handler instead
+ *
+ * Changes made for release in 2.5.35 :
+ * ----------------------------------
+ * - Set dev->trans_start to avoid filling the logs
+ * - Handle better spurious/bogus interrupt
+ * - Avoid deadlocks in mmc_out()/mmc_in()
+ *
+ * Wishes & dreams:
+ * ----------------
+ * - roaming (see Pcmcia driver)

+ * This division was formerly part of NCR and then AT&T.
+ * Wavelan are also distributed by DEC (RoamAbout DS)...
+ *
+ * To know how to use this driver, read the PCMCIA HOWTO.
+ * If you want to exploit the many other fonctionalities, look comments
+ * in the code...
+ *
+ * This driver is the result of the effort of many peoples (see below).
+ */
+
+/* ------------------------ SPECIFIC NOTES ------------------------ */
+/*
+ * Web page
+ * --------
+ * I try to maintain a web page with the Wireless LAN Howto at :
+ * http://www.hpl.hp.com/personal/Jean_Tourrilhes/Linux/Wavelan.html
+ *
+ * SMP
+ * ---
+ * We now are SMP compliant (I eventually fixed the remaining bugs).
+ * The driver has been tested on a dual P6-150 and survived my usual
+ * set of torture tests.
+ * Anyway, I spent enough time chasing interrupt re-entrancy during
+ * errors or reconfigure, and I designed the locked/unlocked sections
+ * of the driver with great care, and with the recent addition of
+ * the spinlock (thanks to the new API), we should be quite close to
+ * the truth.
+ * The SMP/IRQ locking is quite coarse and conservative (i.e. not fast),
+ * but better safe than sorry (especially at 2 Mb/s ;-).
+ *
+ * I have also looked into disabling only our interrupt on the card
+ * (via HACR) instead of all interrupts in the processor (via cli),
+ * so that other driver are not impacted, and it look like it's
+ * possible, but it's very tricky to do right (full of races). As
+ * the gain would be mostly for SMP systems, it can wait...
+ *
+ * Debugging and options
+ * ---------------------
+ * You will find below a set of '#define" allowing a very fine control
+ * on the driver behaviour and the debug messages printed.
+ * The main options are :
+ * o WAVELAN_ROAMING, for the experimental roaming support.
+ * o SET_PSA_CRC, to have your card correctly recognised by
+ * an access point and the Point-to-Point diagnostic tool.
+ * o USE_PSA_CONFIG, to read configuration from the PSA (EEprom)
+ * (otherwise we always start afresh with some defaults)
+ *
+ * wavelan_cs.o is darn too big
+ * -------------------------
+ * That's true ! There is a very simple way to reduce the driver
+ * object by 33% (yes !). Comment out the following line :
+ * #include <linux/wireless.h>
+ * Other compile options can also reduce the size of it...
+ *
+ * MAC address and hardware detection :
+ * ----------------------------------
+ * The detection code of the wavelan chech that the first 3
+ * octets of the MAC address fit the company code. This type of
+ * detection work well for AT&T cards (because the AT&T code is
+ * hardcoded in wavelan_cs.h), but of course will fail for other
+ * manufacturer.
+ *
+ * If you are sure that your card is derived from the wavelan,
+ * here is the way to configure it :
+ * 1) Get your MAC address
+ * a) With your card utilities (wfreqsel, instconf, ...)
+ * b) With the driver :
+ * o compile the kernel with DEBUG_CONFIG_INFO enabled
+ * o Boot and look the card messages
+ * 2) Set your MAC code (3 octets) in MAC_ADDRESSES[][3] (wavelan_cs.h)
+ * 3) Compile & verify
+ * 4) Send me the MAC code - I will include it in the next version...
+ *
+ */
+
+/* --------------------- WIRELESS EXTENSIONS --------------------- */
+/*
+ * This driver is the first one to support "wireless extensions".
+ * This set of extensions provide you some way to control the wireless
+ * caracteristics of the hardware in a standard way and support for
+ * applications for taking advantage of it (like Mobile IP).
+ *
+ * You will need to enable the CONFIG_NET_RADIO define in the kernel
+ * configuration to enable the wireless extensions (this is the one
+ * giving access to the radio network device choice).
+ *
+ * It might also be a good idea as well to fetch the wireless tools to
+ * configure the device and play a bit.

+/*
+ * The history of the Wavelan drivers is as complicated as history of

+ *
+ * All started with Anders Klemets <klemets@paul.rutgers.edu>,
+ * writting a Wavelan ISA driver for the MACH microkernel. Girish
+ * Welling <welling@paul.rutgers.edu> had also worked on it.
+ * Keith Moore modify this for the Pcmcia hardware.
+ *
+ * Robert Morris <rtm@das.harvard.edu> port these two drivers to BSDI
+ * and add specific Pcmcia support (there is currently no equivalent
+ * of the PCMCIA package under BSD...).
+ *
+ * Jim Binkley <jrb@cs.pdx.edu> port both BSDI drivers to FreeBSD.
+ *
+ * Bruce Janson <bruce@cs.usyd.edu.au> port the BSDI ISA driver to Linux.
+ *
+ * Anthony D. Joseph <adj@lcs.mit.edu> started modify Bruce driver
+ * (with help of the BSDI PCMCIA driver) for PCMCIA.
+ * Yunzhou Li <yunzhou@strat.iol.unh.edu> finished is work.
+ * Joe Finney <joe@comp.lancs.ac.uk> patched the driver to start
+ * correctly 2.00 cards (2.4 GHz with frequency selection).
+ * David Hinds <dahinds@users.sourceforge.net> integrated the whole in his
+ * Pcmcia package (+ bug corrections).

+ * displayed at console and still in /var/adm/messages)
+ *
+ * Changes made in fourth release :
+ * ------------------------------

+ * WL3501 Wireless LAN PCMCIA Card Driver for Linux
+ * Written originally for Linux 2.0.30 by Fox Chen, mhchen@golf.ccl.itri.org.tw
+ * Ported to 2.2, 2.4 & 2.5 by Arnaldo Carvalho de Melo <acme@conectiva.com.br>
+ * Wireless extensions in 2.4 by Gustavo Niemeyer <niemeyer@conectiva.com>
+ *
+ * References used by Fox Chen while writing the original driver for 2.0.30:
+ *
+ * 1. WL24xx packet drivers (tooasm.asm)
+ * 2. Access Point Firmware Interface Specification for IEEE 802.11 SUTRO
+ * 3. IEEE 802.11
+ * 4. Linux network driver (/usr/src/linux/drivers/net)
+ * 5. ISA card driver - wl24.c
+ * 6. Linux PCMCIA skeleton driver - skeleton.c
+ * 7. Linux PCMCIA 3c589 network driver - 3c589_cs.c
+ *
+ * Tested with WL2400 firmware 1.2, Linux 2.0.30, and pcmcia-cs-2.9.12
+ * 1. Performance: about 165 Kbytes/sec in TCP/IP with Ad-Hoc mode.
+ * rsh 192.168.1.3 "dd if=/dev/zero bs=1k count=1000" > /dev/null
+ * (Specification 2M bits/sec. is about 250 Kbytes/sec., but we must deduct
+ * ETHER/IP/UDP/TCP header, and acknowledgement overhead)
+ *
+ * Tested with Planet AP in 2.4.17, 184 Kbytes/s in UDP in Infrastructure mode,
+ * 173 Kbytes/s in TCP.
+ *
+ * Tested with Planet AP in 2.5.73-bk, 216 Kbytes/s in Infrastructure mode
+ * with a SMP machine (dual pentium 100), using pktgen, 432 pps (pkt_size = 60)
