In this case the loop was attempting to match SSIDs in the filter
list to this empty entry and marking them as HIDDEN (sending probe

Enable ANI for ar9100 since it seems to be working fine (and as a
matter of fact ANI was always performed for ar9100 since code which
was supposed to disable it didn't achieve this goal).
This patch sets config.enable_ani to default (true) value for
ar9100.

Currently in ath9k code there is an attempt which is meant to
disable ANI for ar9100 and ar9340. But it doesn't really achieve
this. All it does is disable ANI init and setup (i.e. calls to
ath9k_hw_ani_setup and ath9k_hw_ani_init). Since ath9k_hw_ani_setup is
not called ah->config.ani_poll_interval is never initialized (i.e. it
is always zero) and ath_ani_calibrate always executes ANI procedures
(over uninitialized ANI parameters).
Moreover, ath_ani_calibrate is being called each 1ms because
common->ani.timer is set to zero interval because
ah->config.ani_poll_interval==0 (and thus smallest value of all
intervals). Normally it should not be called this often.
This patch changes the code so config.enable_ani is used to check if
ANI should be performed.
config.enable_ani is initialized to true by default. This patch sets
it to false for ar9100 and ar9340.

Recently more places in mac80211 call drv_flush to ensure proper order
for state changes wrt. powersave, channel changes, etc. On some systems
such calls lead to spurious logspam about failing to stop tx dma, as well
as hardware resets that go along with that.
Instead of dropping packets in a place where it's completely unnecessary,
only do it when drop == true.

Turning off the radio when mac80211 tells the driver that it's idle is not
a good idea, as idle interfaces might still occasionally scan or send packets.
The only time the radio can be safely turned off is when drv_stop has been
called. In the mean time, use sc->ps_idle only to indicate network sleep vs
full sleep.
Move the LED GPIO changes out of the PCI suspend/resume path, the start/stop
functions already take care of that.

After waking up from full sleep, registers are accessible, but rx/tx
typically fails. A fast channel change will not recover from this, so
ensure that a full-sleep -> wake transition is always followed by a full
reset.
The reason why this hasn't created any serious problems yet is that it's
hidden by the (wrong) behavior of enabling/disabling the radio when the
wiphy idle state changes.
