mac80211: explicitly disable/enable QoS
mac80211 is telling drivers, in particular
iwlwifi, whether QoS is enabled or not.
However, this is only relevant for station mode,
since only then will any device send nullfunc
frames and need to know whether they should be
QoS frames or not. In other modes, there are
(currently) no frames the device is supposed to
send.
When you now consider virtual interfaces, it
becomes apparent that the current mechanism is
inadequate since it enables/disables QoS on a
global scale, where for nullfunc frames it has
to be on a per-interface scale.
Due to the above considerations, we can change
the way mac80211 advertises the QoS state to
drivers to only ever advertise it as "off" in
station mode, and make it a per-BSS setting.

An A-MPDU may contain several subframes each containing its own
CRC for the data. Each subframe also has a respective CRC for the
MPDU length and 4 reserved bits (aka delimeter CRC). AR9003 will
ACK frames that have a valid data CRC but have failed to pass the
CRC for the MPDU length, if and only if the subframe is not the
last subframe in an A-MPDU and if an OFDM phy OFDM reset error has
been caught. Discarding those subframes results in packet loss under
heavy stress conditions, an example being UDP video. Since the
frames are ACK'd by hardware we need to let these frames through
and process them as valid frames.

The rt2x00dev->intf_work workqueue is never initialized when a driver is
probed for a non-existent device (in this case rt2500usb). On such a
path we call rt2x00lib_remove_dev() to free any resources initialized
during the probe before we use INIT_WORK to initialize the workqueue.
This causes lockdep to get confused since the lock used in the workqueue
hasn't been initialized yet but is now being acquired during
cancel_work_sync() called by rt2x00lib_remove_dev().
Fix this by initializing the workqueue first before we attempt to probe
the device. This should make lockdep happy and avoid breaking any
assumptions about how the library cleans up after a probe fails.
phy0 -> rt2x00lib_probe_dev: Error - Failed to allocate device.

There were a few places where the sc->rxlink pointer was set to NULL "just in
case". This helps nothing - quite to the contrary it is problematic since it
can create self-linked rx descriptors in the middle of the list of receive
buffers.
Here is an example how this could happen (thanks Bob!):
cpu 0: cpu 1:
ath5k_rx_stop
ath5k_tasklet_rx
sc->rxlink = NULL; /* just in case */
// following doesn't link used
// buffer to prev.
ath5k_rxbuf_setup()
In the case of ath5k_rx_stop() and ath5k_stop_locked() buffers/descriptors are
not changed so rxlink should not be changed as well.
In ath5k_intr() we seem to try to work around a hardware bug, as the comment
(which is copied 1:1 from the HAL) suggests. I don't see how this could help.
Also the HAL does not set rxlink in this case (So where does this code come
from? It has been there since the first import of ath5k). Changed to just
increment a statistics counter.
After this patch rxlink is only set to NULL before we initialize rx descriptors
and updated when the descriptors are linked together.

Based on a patch from Bruno Randolf, attempting useful
work while we are resetting the chip just leads to interface
lockups and bad descriptor data, and possibly DMAing to
freed buffers. Let's suspend all tasklets while
reprogramming the registers in the card to avoid such
problems.
In the future we can convert the tasklets to threaded
interrupt handlers to simplify things.

We currently trigger a reset via a tasklet when certain error
conditions are detected so that the card will (eventually)
restart. Unfortunately this makes locking complicated since
reset can also be called in process context (e.g. for channel
change). Currently nothing protects against concurrent resets,
which can be the source of corruption bugs.
Reset takes too long to spinlock the whole thing, so this
patch moves deferred resets into the mac80211 workqueue to
enable use of sc->lock mutex.

AR5008+ and AR9003 currently use two separate implementations of the
ath9k_hw_loadnf function. There are three main differences:
- PHY registers for AR9003 are different
- AR9003 always uses 3 chains, earlier versions are more selective
- The AR9003 variant contains a fix for NF load timeouts
This patch merges the two implementations into one, storing the
register array in the ath_hw struct. The fix for NF load timeouts is
not just relevant for AR9003, but also important for earlier hardware,
so it's better to just keep one common implementation.

If the receive path gets stuck, a full hardware reset is necessary to
recover from it. If this happens during a scan, the whole scan might fail,
as each channel change bypasses the full reset sequence.
Fix this by resetting the fast channel change flag if stopping the
receive path fails.
This will reduce the number of error messages that look like this:
