Lennert Buytenhek 54bc3a0d7a mwl8k: allow for different receive descriptor formats
As the receive descriptor format is determined by the firmware running
on the hardware and not by the hardware itself, and as these
descriptor formats vary a bit between different firmware releases,
abstract out the receive descriptor init/refill/process methods, and
allow choosing between different formats at run time depending on the
chip and firmware we're running on.

Johannes Berg af81858172 mac80211: async station powersave handling
Some devices require that all frames to a station
are flushed when that station goes into powersave
mode before being able to send frames to that
station again when it wakes up or polls -- all in
order to avoid reordering and too many or too few
frames being sent to the station when it polls.

Normally, this is the case unless the station
goes to sleep and wakes up very quickly again.
But in that case, frames for it may be pending
on the hardware queues, and thus races could
happen in the case of multiple hardware queues
used for QoS/WMM. Normally this isn't a problem,
but with the iwlwifi mechanism we need to make
sure the race doesn't happen.

This makes mac80211 able to cope with the race
with driver help by a new WLAN_STA_PS_DRIVER
per-station flag that can be controlled by the
driver and tells mac80211 whether it can transmit
frames or not. This flag must be set according to
very specific rules outlined in the documentation
for the function that controls it.

When we buffer new frames for the station, we
normally set the TIM bit right away, but while
the driver has blocked transmission to that sta
we need to avoid that as well since we cannot
respond to the station if it wakes up due to the
TIM bit. Once the driver unblocks, we can set
the TIM bit.

Similarly, when the station just wakes up, we
need to wait until all other frames are flushed
before we can transmit frames to that station,
so the same applies here, we need to wait for
the driver to give the OK.

Subject: BUG: oops when "rmmod ipw2200"

This happened on wireless-testing v2.6.32-rc6-41575-g5e68bfb. I
modprobed ipw2200, put it into monitor mode, used tshark a while to
monitor, then I stopped tshark, "ifconfig eth2 down" and finally
"rmmod ipw2200", and voila:
