2010-01-12mwl8k: post per-vif firmware commands as per-vif commandsLennert Buytenhek1-23/+26
SET_BEACON, SET_MAC_ADDR, BSS_START and SET_NEW_STN are the currently supported firmware commands that are actually per-vif commands. Use mwl8k_post_pervif_cmd() for these commands, so that the macid of the vif they operate on gets passed down into the firmware.

2010-01-12mwl8k: prepare for posting per-vif firmware commandsLennert Buytenhek1-1/+16
One of the bytes in the mwl8k firmware command header is the 'macid' byte, which for per-vif commands indicates which of the BSSes this command is intended for. (For commands that are not per-vif commands, this byte can just be 0.) This patch adds mwl8k_post_pervif_cmd(), which will take the macid assigned to this interface (to be done in ->add_interface()), copy it into the command packet macid field, and post the command as usual.

2010-01-12mwl8k: use firmware capability field to decide which bands to registerLennert Buytenhek1-6/+25
Make the decision about whether to register the 2.4 and 5 GHz bands with mac80211 by looking at the capability field in GET_HW_SPEC (STA firmware only for now). This enables 5 GHz STA operation.

2010-01-12mwl8k: handle 5 GHz legacy rate bitmaps in firmware commandsLennert Buytenhek1-5/+25
Whenever mac80211 gives us a legacy rate bitmap in the context of the 5 GHz band, we need to remember to shift the bitmap left by 5 positions before giving it to the firmware, as the firmware follows the bitmap bit assignment of the 2.4 GHz rate table even if we're on the 5 GHz band, and the 2.4 GHz rate table includes five non-OFDM rates at the start that are not valid in the 5 GHz band.

2010-01-12mwl8k: properly set receive status rate index on 5 GHz receiveLennert Buytenhek1-2/+14
The mwl8k firmware uses indices into the 2.4 GHz band rate table for the receive descriptor channel field even if the packet was received on a 5 GHz channel, while mac80211 expects an index into the 5 GHz band rate table when packets are received on the 5 GHz band, which presents a mismatch as the 5 GHz band rate table lacks the five non-OFDM rates that the 2.4 GHz rate table starts with. To handle this properly, we need to substract 5 from the rate index field if the packet was received on a 5 GHz channel (and was not received at an MCS rate).

2010-01-12mac80211: check uapsd state for dynamic power saveKalle Valo1-0/+25
To make U-APSD client mode effective, we must not wake up from dynamic power save when transmitting frames. So if dynamic power save is enabled, it needs check the queue the transmitted packet is in and decide if we need to wake up or not. In a perfect world, where all packets would have correct QoS tags, U-APSD enabled queues should not trigger wakeup from power save. But in the real world, where very few packets have correct QoS tags, this won't work. For example, if only voip class has U-APSD enabled and we send a packet in voip class, but the packets we receive are in best effort class, we would receive the packets with the legacy power save method. And that would increase latencies too much from a voip application point of view. The workaround is to enable U-APSD for all qeueus and still use dynamic ps wakeup for all other queues except voip. That way we can still save power with a voip application and not sacrifice latency. Normal traffic (in background, best effort or video class) would still trigger wakeup from dynamic power save.

2010-01-12mac80211: create tx handler for dynamic psKalle Valo1-40/+41
Currently dynamic ps check is in ieee80211_xmit(), but it's cleaner to have a separate tx handler for this. Also this is a prerequisite for U-APSD client mode which needs to know the queue frame is in. Also need_dynamic_ps() function is embedded to the tx handler. No functional changes expect that the code is run in a later phase than originally. Signed-off-by: Kalle Valo <kalle.valo@nokia.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2010-01-12mac80211: add U-APSD client supportKalle Valo9-6/+106
Add Unscheduled Automatic Power-Save Delivery (U-APSD) client support. The idea is that the data frames from the client trigger AP to send the buffered frames with ACs which have U-APSD enabled. This decreases latency and makes it possible to save even more power. Driver needs to use IEEE80211_HW_UAPSD to enable the feature. The current implementation assumes that firmware takes care of the wakeup and hardware needing IEEE80211_HW_PS_NULLFUNC_STACK is not yet supported.

2010-01-12mac80211: flush workqueue before calling driver ->stop() methodLennert Buytenhek1-1/+1
Since commit "mwl8k: handle station database update for AP's sta entry via ->sta_notify()", mwl8k every now and then gets a command timeout when ifconfig'ing a STA interface down. This turns out to be due to mwl8k_stop() being called while the work queue item that was scheduled by mwl8k_sta_notify() to remove the STA entry for the associated AP is still queued, and the former disables interrupts so that when the latter eventually runs, a command completion interrupt is never seen. Fix this by changing ieee80211_stop_device() so that the workqueue is flushed before drv_stop() is called, instead of doing it the other way around as is done now. (As ->stop() is allowed to sleep, there isn't any reason for drivers to queue work from within it.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

IEEE80211_AMPDU_TX_OPERATIONAL is a valid action, just iwlwifi driver do not need to take any action for it; so instead of return "-EINVAL", it is a good program practice to return "-EOPNOTSUPP" to make sure mac80211 will not get wrong impression.

2010-01-12mwl8k: move receive processing to taskletLennert Buytenhek1-10/+37
Like how TX reclaim is done in a tasklet, move receive processing to tasklet context as well. This can have nice benefits for CPU utilisation and throughput, especially at 3-stream rates. (Use the same CLEAR_SEL trick as the TX reclaim tasklet does, to avoid having to touch the interrupt mask registers.) Signed-off-by: Lennert Buytenhek <buytenh@marvell.com> Signed-off-by: John W.

2010-01-12mwl8k: keep TX_DONE interrupt masked while transmit reclaim is runningLennert Buytenhek1-31/+46
By making use of the CLEAR_SEL feature of the mwl8k host interface interrupt controller, we can keep the TX_DONE interrupt source masked while the transmit reclaim tasklet is running (NAPI style) without having to touch the interrupt controller's interrupt mask register when entering or exiting polling mode, and without having to do any more register reads/writes than we do now. When CLEAR_SEL is enabled on the TX_DONE interrupt source, reading the interrupt status register will clear the TX_DONE status bit if it was set, allowing it to be set again if a new TX_DONE event arrives while we are running the TX reclaim tasklet, but such a new event will then not trigger another PCI interrupt until a zero is written to the TX_DONE interrupt status register bit. I.e., if we write a zero to the TX_DONE interrupt source bit in the interrupt status register when the TX reclaim tasklet thinks it's done, a PCI interrupt will be triggered if a new TX_DONE event arrived from the hardware between us deciding that there is no more work to do and re-enabling the TX_DONE interrupt source, thereby avoiding the classic NAPI poll mode exit race that would otherwise occur.

2010-01-12mwl8k: bump the transmit wait timeout to 5 secondsLennert Buytenhek1-1/+1
While it is reasonable to expect that at least one transmit ring entry will be processed per second while we are waiting for the transmit rings to drain, the firmware can end up doing batching of transmit ring status writeback, which means that the transmit rings can appear stuck for more than a second at a time.
