Since different teams want it in different formats, dump

While at it - make this code slightly more robust by making
the required verification on the offsets / length in the
write handler.
iwlwifi: mvm: disable the device as soon as RFKILL fires
The firmware needs to be stopped quickly (100ms) after the
RFKILL interrupt fired. Failing to do so would allow the
firmware to access the radio registers which would lead to
a hardware error.
Before this change, we would kill the firmware only when
mac80211 stops the device which can take a fair amount of
time. Take a shortcut by stopping the device right away
in the interrupt.
This is not relevant if the current firmware is INIT
firmware since that firmware can run while in RFKILL.
iwlwifi: pcie: allow the op_mode to call stop_device whenever it wants
Calling stop_device when start_fw wasn't called would issue:
Stopping tx queues that aren't allocated...
Also allow the op_mode to call stop_device and then to
disable the Tx queues - in that case just silently ignore
the disabling on the Tx queues, since the PRPH registers
aren't reachable any more.
iwlwifi: pcie: don't update the op_mode if rfkill hasn't changed
This is useless and introduces a dependency between rfkill
and stop_device - the op_mode can't call stop_device from
the rfkill notification since it would lead to an endless
recursion.
Next patches will need to do so.
iwlwifi: pcie: keep the NIC awake when commands are in flight
Under very specific circumstances, the firmware might
ignore a host command. This was debugged and we ended up
seeing that the power management hardware was faulty.
In order to workaround this issue, we keep the NIC awake
as long as we have host commands in flight. This will avoid
to put the hardware into buggy condition.
The AC / fifo mapping was wrong - BE packets landed in VO
FIFO. The iwl_mvm_tx_fifo enumeration isn't in the same
order as ieee80211_ac_numbers enumeration.
Since the firmware relies on fifo / ac mapping - this led
to wrong behavior. E.g. the firmware sends beacon with the
same QoS parameters as VO, and it actually took the
parameters of BK. There are probably more severe issues.

mac80211: fix iflist_mtx/mtx locking in radar detection
The scan code creates an iflist_mtx -> mtx locking dependency,
and a few other places, notably radar detection, were creating
the opposite dependency, causing lockdep to complain. As scan
and radar detection are mutually exclusive, the deadlock can't
really happen in practice, but it's still bad form.
A similar issue exists in the monitor mode code, but this is
only used by channel-context drivers right now and those have
to have hardware scan, so that also can't happen.
Still, fix these issues by making some of the channel context
code require the mtx to be held rather than acquiring it, thus
allowing the monitor/radar callers to keep the iflist_mtx->mtx
lock ordering.
While at it, also fix access to the local->scanning variable
in the radar code, and document that radar_detect_enabled is
now properly protected by the mtx.
All this would now introduce an ABBA deadlock between the DFS
work cancelling and local->mtx, so change the locking there a
bit to not need to use cancel_delayed_work_sync() but be able
to just use cancel_delayed_work(). The work is also safely
stopped/removed when the interface is stopped, so no extra
changes are needed.
