Whenever the regulatory got updated by country IE for the world
roaming cards, need to reconfigure the tx power immediately to
increase the power level.

When we receive a country IE hint and we have a world roaming card
we can optimize output power further by ensuring that we use the
calibrated data for the country by using that country's own CTL data.
That is -- when world roaming and when we process a country IE we
no longer need to use the lowest output power of all CTLs instead
we use an optimized CTL output power for that specific country.
We accomplish this by copying the regulatory data prior on init
and restoring it when cfg80211 tells us it gets a core hint. Core
hints are only sent on init and when it wants to restore reguulatory
settings. We take advantage of this fact and apply the cached
regulatory data when we get a core hint. When we get a country IE
hint though we process the regulatory data as if programmed for
a specific country.

This has no functional change. The helper can be used later
for other things like country IE changes and following the CTL

in my previous patches of handling MCI interrupt I overlooked
the case of interrupt status/mask variable being zeroed out in
the below code, so ath_isr does not cache the MCI interrupt
in the intrstatus. finally MCI interrupt handling won't be
handled in ath9k_tasklet for the scheduled interrupts.
Fix this by moving the MCI interrupt code in the appropriate
position in ar9003_hw_get_isr

ath6kl firmware supports scheduled scan functionality with the wow ssid
filter. But the firmware does not send any events after scan results
so I had to add a timer which notifies about new scan results.
Sched scan needs firmware version 3.2.0.6 or later. If firmware doesn't
support sched scan the driver will not enable the feature.

For some strange reason I used ALIGN() to calculate index to the
buffer. That is totally bogus and wouldn't work when it tried to read
the second bit. Fix it by removing the ALIGN() altogether.
Also check that ie_len is not too short.

This way it's possible to keep all disconnect logic in one function and
easier to add new functionality, like stopping scheduled scan.
There are some changes to commands called during network interface close,
but there should not be any visible changes in functionality.

There's a workaround in ath6kl_cfg80211_stop() which emits disconnected
even when sme_state was disconnected. This is legacy from the old
staging driver and I can't repoduce the old problem anymore. I assume the
bug got fixed while the driver was cleaned up so let's get
rid of the hack.
This makes it possible to call ath6kl_cfg80211_stop from ath6kl_close()
which happens in a followup patch.

The stations always chooses 1Mbps for all trasmitting frames,
whenever the AP is configured to lock the supported rates.
As the max phy rate is always set with the 4th from highest phy rate,
this assumption might be wrong if we have less than that. Fix that.

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.

here we check for BT state and if BT calibration has started,
give 25ms for BT Calibration to finish. we also take care of 2G/5G
switch and LNA transfer incase WLAN is operating in 5G. in case the BT
state is awake when we do WLAN calibration re-calibrate and we reset
the message exchange between WLAN and BT. BT is given preference when
simultaneous CAL request happens. calibration for WLAN/BT is done
assuming that the other co-existing module is in awake state, if not
we continue to do calibration while if the other module's state changes
we need to do restart the calibration handshake
