Problem: If setting of an ip-address fails with LAN_OFFLINE,
qeth does not save the ip-address in its internal
list of set ip-addresses. qeth recovers after a
following STARTLAN event, but cannot set the unsaved
ip-address.
Solution: save the ip-address in the qeth-maintained list of
ip-addresses after a LAN_OFFLINE failure for SETIP.

Symptom: slow CCL response time
Problem: non-ETH_P_802_2 packets are not delivered to NDH for
CCL. But CCL detects missing sequence numbers, which
cause a serious performance problem with CCL.
Solution: assign sequence numbers only to 802.2 packets.

Problem: A STARTLAN command from the adapter may arrive while a
qeth recovery is currently running with a failed qeth
STARTLAN. Usually qeth schedules a recovery when
receiving a STARTLAN command from the adapter. But
another recovery scheduled while a recovery is already
running never starts. Thus the qeth-administered
lan_online flag remains zero in this scenario, even
though the adapter-STARTLAN has happened.
Solution: Set lan_online flag for a received STARTLAN from the
adapter in case scheduled recovery does not start.

1. ip_list handling after deregister failure of multicast address:
If error code "MC Address not found" is returned do not re-add
multicast address to ip_list.
For other error codes readd multicast address at the end of
function qeth_delete_all_mc.
2. ip_list handling after deregister failure or normal ip address:
If error code "IP Address not found" is returned do not re-add
multicast address to ip list.
This is especially important in IP address takeover scenarios,
to enable re-takeover of a taken over IP address.

This patch works around the MWI bug on the DC21143 rev 65 Tulip by
ensuring that the receive buffers don't end on a cache line boundary
(as documented in the errata).
This patch is required for the MIPS based Cobalt Qube/RaQ as
supporting the extra PCI commands seems to reduce the chance of a hard
lockup between the Tulip and the PCI bridge.

winbond-840 shares tulip.h with the tulip driver, because they share
many (but not all) of the same register definitions.
This is useful for the register definitions, but not helpful when it
comes to symbols that are shared among the tulip driver's C modules,
but not meant to be shared outside that one driver.
Thus, PKT_BUF_SZ is a symbol internal to tulip, but it was intruding
upon a similar symbol in winbond-840's namespace. This was not a
problem as long as the two symbols had the same value, but upcoming
patches result in differing symbol values.

This patch revises the logging for link informations of spidernet.

In addition to the value of GHIINT0STS, spidernet interrupt handler
should check the values of GHIINT1STS/GHIINT2STS registers at the
beginning of spider_net_interrupt() so as not to drop error
interrupts.
GHIINT1STS/GHIINT2STS registers indicates some of erroneous conditions
in spidernet, and a few bits of GHIINT0STS register reflects these
conditions. But GHIINT0MSK masks these bits, so you should check these
conditions by reading GHIINT1STS/GHIINT2STS registers directly.

The alloc_netdev_mq() tries to produce 32-bytes alignment for both
the net_device itself and its private data. The second alignment is
achieved by adding the NETDEV_ALIGN_CONST to the whole size of
the memory to be allocated.
However, for those devices that do not need the private area, this
addition just makes the net_device weight 1024 + 32 = 1068 bytes,
i.e. consume twice as much memory.
Since loopback device is such (sizeof_priv == 0 for it), and each
net namespace creates one, this can save a noticeable amount of
memory for kernel with net namespaces turned on.
After this set the lo device is actually allocated from a size-1024
kmem cache on i386 box even with NETPOLL and WIRELESS_EXT turned on.
