it:
eeprom.c: In function 'ath5k_eeprom_read_turbo_modes':

Comparing the code to the Atheros HAL, it's clear that the split between

The Atheros HAL reads both turbo and non-turbo data from EEPROM in one

broke injection of non-broadcast frames to unassociated stations

This patch restores the old behavior, fixing the aforementioned

Also, consistently check for IEEE80211_TX_CTL_INJECTED instead of
iwl_is_monitor_mode in the TX path, as TX_CTL_INJECTED specifically

cfg80211: clean up properly on interface type change
When the interface type changes while connected, and the
driver does not require the interface to be down for a
type change, it is currently possible to get very strange
results unless the driver takes special care, which it
shouldn't have to.
To fix this, take care to disconnect/leave IBSS when
changing the interface type -- even if the driver may fail
the call. Also process all events that may be pending to
avoid running into a situation where an event is reported
but only processed after the type has already changed,
which would lead to missing events and warnings.
A side effect of this is that you will have disconnected
or left the IBSS even if the mode change ultimately fails,
but since the intention was to change it and thus leave or
disconnect, this is not a problem.

to a race condition between drivers and userspace,
when the driver reports joined but the user in the
meantime decided to leave the IBSS again, the warning
would trigger. This was made more likely by kmemcheck
delaying the code that does the check and sends the
event.
So first, make the warning trigger closer to the
driver, which means it's not locked, but since only
the warning depends on it that's ok.
And secondly, users will not want to have spurious
warnings at all, so make those that are known to be
racy in such a way configurable.

ath9k: Fix chainmask selection during scanning
The TX/RX chainmasks were set to 1x1 during scanning.
Configure them properly with the values retrieved from
the EEPROM.
Also, this requires scan_start/scan_end callbacks to be
locked with sc->mutex.

cfg80211: check lost scans later, fix bug
When we lose a scan, cfg80211 tries to clean up after
the driver. However, it currently does this too early,
it does this in GOING_DOWN already instead of DOWN, so
it may happen with mac80211. Besides fixing this, also
make it more robust by leaking the scan request so if
the driver later actually finishes the scan, it won't
crash. Also check in ___cfg80211_scan_done whether a
scan request is still pending and exit if not.

mac80211: fix configure_filter invocation after stop
Since configure_filter can sleep now, any multicast
configuration needed to be postponed to a work struct.
This, however, lead to a problem that we could queue
the work, stop the device and then afterwards invoke
configure_filter which may lead to driver hangs and is
a bug. To fix this, we can just cancel the filter work
since it's unnecessary to do after stopping the hw.
Since there are various places that call drv_stop, and
two of them do very similar things, the code for them
can be put into a shared function at the same time.
