iwlwifi: do not set tx power when channel is changing
we set device tx power during initialization to priv->tx_power_next,
which itself is initialized to minimum power. That changed
default behaviour of driver. Previously we initialized device to
transmit at maximum available power by default. Patch change again
to previous behaviour and cleanup tx power initialization.
Fortunately this is not critical fix, as mac80211 layer setup
tx power lately to 14dB, hence device does not operate at minimal
transmit power all the time.

"For best CPU usage and power consumption, having as few

desirable. Hence, the hardware should filter as much
as possible."
Note: Not all firmwares include the multicast filter
feature and the stack does not filter them either.
The ARP filter on the other hand was dropped from the
patch since it does not work correctly:
Quote from: Max Filippov <jcmvbkbc@gmail.com>
<http://www.spinics.net/lists/linux-wireless/msg67466.html>
"In the ARP case, when there's no other traffic on p54spi,
all ARP requests are dropped. But if there's some egress
traffic from p54spi, filter seems to work correctly:
only ARP requests that match filter pass through.
In the multicast case filter seems to work correctly, but
it treats broadcast as subject to that filtering too. By
default only 01:00:5e:00:00:01 gets into priv->mc_maclist,
so we miss all broadcasts.
These two filters seem to interfere:
- if we set ARP filter and multicast filter without bc
=> we miss all ARPs if there's no egress traffic;
- if we set ARP filter and multicast filter with bc or
don't set mc filter at all => we get all ARPs.
This effect does not depend on filter setup order."

ath9k_hw: Fix Tx IQ Calibration hang issue in AR9003 chips
On AR9003 chips, doing three IQ calibrations will possibly cause chip
in stuck state. In noisy environment, chip could receive
a packet during the middle of three calibrations and it causes
the conflict of HW access and the eventual failure. It also
causes IQ calibration outliers which results in poor Tx EVM.
The IQ Cal procedure is after resetting the chip, run IQ cal 3 times
per each cal cycle and find the two closest readings and average of two.
The advantage of running Tx IQ cal more than once is that we can compare
calibration results for the same gain setting over multiple iterations.
Most of the cases the IQ failures were observed after first pass.
For the AR9485 and later chips, Tx IQ Calibration is performed along
with AGC cal. But for pre-AR9485 chips, Tx IQ cal HW has to be separated
from the rest of calibration HW to avoid chip hang. After all
calibrations are done in HW, we can start SW post-processing.
By doing this way, we minimize the SW difference among all chips.
The order of calibration (run IQ cal before other calibration) is also
needed to avoid chip hang for chips before AR9485. This issue was
originally observed with AR9382.
During the issue kernel log was filled with following message
ath: timeout (100000 us) on reg 0xa640: 0x00000001 & 0x00000001 != 0x00000000

We need not wake up the chip even before mutex lock is acquired and also
that it is required only if we are going to drain the txq. So place the
wrappers accordingly and this change is also useful when there are no
pending frames in the txq as we do not wake up the chip unnecessarily.

ath9k_hw: Fix incorrect baseband PLL phase shift for AR9485
we should program the AR9485 baseband PLL phase shift to 6 and
a redundant setting overwrites the correct value. Remove the
incorrect and unwnated register setting.

cfg80211: module_param to disable HT40 in 2.4GHz band
Currently mac80211 uses ieee80211_disable_40mhz_24ghz module
parameter to allow disabling 40MHz operation in the 2.4GHz band.
Move this handling from mac80211 to cfg80211 so that the feature
will be more generic.

Hw next tigger time is configured as current_tsf + (timer_period * 10) which
is wrong, it should be current_tsf + timer_period. The wrong hw timer configuration

mac80211: tear down BA sessions properly on suspend
Currently, the code to tear down BA sessions will
execute after queues are stopped, but attempt to
send frames, so those frames will just get queued,
which isn't intended. Move this code to before to
tear down the sessions properly.
Additionally, after stopping queues, flush the TX
queues in the driver driver to make sure all the
frames went out.
