76a029fbfb wl1271: Fix scan race condition
In the scan state machine, the wl1271_mutex is unlocked first then relocked,
and then the scan state variables are modified.

This makes it possible for ieee80211_scan_complete to be called twice in some
scenarios, as the scan completion event from the firmware may be processed
while the mutex is unlocked.

To fix the issue, move the ieee80211_scan_complete call last in the function.
This is generally safer, but there still may be issues is functions calling
the scan state machine rely on states checked before the unlocking of the
global mutex.

(forward ported from 2.6.32 -- this is not strictly needed anymore, because
the mutex doesn't need to be unlocked anymore, but I'm applying this change
anyway, so that the call to ieee80211_scan_complete is in the same place)

"!ai->config.rates[i]".

This option was just used for development and it wasn't documented

90fa539ca3 ath9k: clean up / fix aggregation session flush
The tid aggregation cleanup is a bit fragile, as it discards failed
subframes in some places, and retransmits them in others. This could
block the cleanup of an existing aggregation session, if a retransmission
for a tid is issued, yet the tid is never scheduled again because of
the cleanup state.

Fix this by getting rid of as many subframes as possible, as early
as possible, and immediately transmitting pending subframes as regular
HT frames instead of waiting for the cleanup to complete.

Drop all pending subframes while keeping track of the Block ACK window
during aggregate tx completion to prevent sending out stale subframes,
which could confuse the receiver side.

234132960d ath5k: Keep last descriptor in queue
If we return a TX descriptor to the pool of available descriptors, while a
queues TXDP still points to it we could potentially run into all sorts of
troube.

It has been suggested that there is hardware which can set the descriptors
done bit before it reads ds_link and moves on to the next descriptor. While the
documentation says this is not true for newer chipsets (the descriptor contents
are copied to some internal memory), we don't know about older hardware.

To be safe, we always keep the last descriptor in the queue, and avoid dangling
TXDP pointers. Unfortunately this does not fully resolve the problem - queues
still get stuck!

This is similar to what ath9k does.

Prepare ath5k for WME by using four hardware queues.

The way we set up our queues matches the mac80211 queue priority 1:1, so we
don't have to do any mapping for queue numbers.

Every queue uses 50 of the total 200 available transmit buffers, so the DMA
memory usage does not increase with this patch, but it might be good to
fine-tune the number of buffers per queue later (depending on the CPU speed and
load, and the speed of the medium access, it might not be big enough).

AESCCM flag for ath9k. common ath code still needs a flag for this because
there is ath5k hardware which can't do AES in hardware.
