configures all the supported channels for scanning.
However, this can result in SYSASSERT in some cases,
when the configured channel is disabled.
Instead, configure only the channels given in the

As the spec mandates, flush data in the AP path before transmitting the

dropped in the Tx path.
For the teardown flow, flush all packets in the direct path before

is sent, forcing all subsequent Tx to the peer through the AP.
Make sure to flush the queues when disabling the link to get the

In some cases we may want to stop the queues of a single vif (for
instance during a channel-switch). Add a function that stops all the
queues that are assigned to a vif. If a queue is assigned to more
than one vif, the corresponding netdev subqueue of the other vif(s)
will also be stopped. If the HW doesn't set the
IEEE80211_HW_QUEUE_CONTROL flag, then all queues are stopped.
Also add a corresponding function to wake the queues of a vif back.

Sometimes different vifs may be stopping the queues for the same
reason (e.g. when several interfaces are performing a channel switch).
Instead of using a bitmask for the reasons, use an integer that holds
a refcount instead. In order to keep it backwards compatible,
introduce a boolean in some functions that tell us whether the queue
stopping should be refcounted or not. For now, use not refcounted for
all calls to keep it functionally the same as before.

Currently, cfg80211 tries to implement ethtool, but that doesn't
really scale well, with all the different operations. Make the
lower-level driver responsible for it, which currently only has
an effect on mac80211. It will similarly not scale well at that
level though, since mac80211 also has many drivers.

The mesh_plink code is doing some interesting things with the
ignore_plink_timer flag. It seems the original intent was to
handle this race:
cpu 0 cpu 1
----- -----
start timer handler for state X
acquire sta_lock
change state from X to Y
mod_timer() / del_timer()
release sta_lock
acquire sta_lock
execute state Y timer too soon
However, using the mod_timer()/del_timer() return values to
detect these cases is broken. As a result, timers get ignored
unnecessarily, and stations can get stuck in the peering state
machine.
Instead, we can detect the case by looking at the timer expiration.
In the case of del_timer, just ignore the timers in the following
(LISTEN/ESTAB) states since they won't have timers anyway.

It is currently possible to have a race due to the station PS
unblock work like this:
* station goes to sleep with frames buffered in the driver
* driver blocks wakeup
* station wakes up again
* driver flushes/returns frames, and unblocks, which schedules
the unblock work
* unblock work starts to run, and checks that the station is
awake (i.e. that the WLAN_STA_PS_STA flag isn't set)
* we process a received frame with PM=1, setting the flag again
* ieee80211_sta_ps_deliver_wakeup() runs, delivering all frames
to the driver, and then clearing the WLAN_STA_PS_DRIVER and
WLAN_STA_PS_STA flags
In this scenario, mac80211 will think that the station is awake,
while it really is asleep, and any TX'ed frames should be filtered
by the device (it will know that the station is sleeping) but then
passed to mac80211 again, which will not buffer it either as it
thinks the station is awake, and eventually the packets will be
dropped.
Fix this by moving the clearing of the flags to exactly where we
learn about the situation. This creates a problem of reordering,
so introduce another flag indicating that delivery is being done,
this new flag also queues frames and is cleared only while the
spinlock is held (which the queuing code also holds) so that any
concurrent delivery/TX is handled correctly.
