This patch adds a new event to the Management interface to track when
local adapters are discovering remote devices. For now this only tracks

This patch adds start_discovery and stop_discovery commands to the
management interface. Right now their implementation is fairly
simplistic and the parameters are fixed to what user space has
defaulted to so far.
This is the very initial phase for discovery implementation into
the kernel. Next steps include name resolution, LE scanning and
bdaddr type handling.

    iwlwifi: sanity check before counting number of tfds can be free

we use skb->data after calling ieee80211_tx_status_irqsafe(), which
could free skb instantly.

On current kernels I do not observe practical problems related with
bug, but on 2.6.35.y it cause random system hangs when stressing
wireless link, making bisection of other problems impossible.

The locking with SMPS requests means that the
debugs file should lock the mgd mutex, not the
iflist mutex. Calls to __ieee80211_request_smps()
need to hold that mutex, so add an assertion.

This has always been wrong, but for some reason
never been noticed, probably because the locking
error only happens while unassociated.

The patch 'ath9k_hw: fix stopping rx DMA during resets' added code to detect
a condition where rx DMA was stopped, but the MAC failed to enter the idle
state. This condition requires a hardware reset, however the return value
of ath_stoprecv was 'true' in that case, which allowed it to skip the reset
when issuing a fast channel change.

In the teardown path the reset command is sent to the controller,
this event causes the command timer to be reactivated.

So the timer is removed in two situations, when the adapter isn't
marked as UP and when we know that some command has been sent.
