commit d05c806 ("wl12xx: rearrange some ELP wake_up/sleep calls")
introduced a bug in which wl1271_ps_elp_wakeup() was called instead
of wl1271_ps_elp_sleep() after completing the tx work.
mwl8k: Reducing extra_tx_headroom for tx optimization in AP mode
The tx_headroom required for mwl8k driver is 32 bytes and it
can use the space for 802.11 header received from mac80211.
mwl8k considers the smallest 802.11 frame (CTS2self of 10
bytes) that can be received from mac80211 to compute the
extra_tx_headroom as 22 (32 - 10) bytes.
When the wireless interface is part of bridge, this
extra_tx_headroom requirement results in a memcpy in
mac80211 (in function pskb_expand_head) for all the data
frames needing L2 forwarding/bridging, when NET_SKB_PAD is
defined as 32. This patch reduces the extra_tx_headroom by
8 bytes so that memcpy of data frames in mac80211 is
avoided in this case.
The resize will be required in driver for frames with 802.11
header size of less than 18 bytes.

To fix introduce additional CMD_MAPPED to mark command as mapped and
serialize iwl_enqueue_hcmd() with iwl_tx_cmd_complete() using
hcmd_lock. Serialization will also fix possible race conditions,
because q->read_ptr, q->write_ptr are modified/used in parallel.

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.

"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."

My 14e4:4315 is SSB_IDLOW_SSBREV_26:
read32 0xfaafcff8 -> 0x600422d5
My 14e4:4328 is SSB_IDLOW_SSBREV_24:
read32 0xfaafcff8 -> 0x400422c5
My 14e4:432b is SSB_IDLOW_SSBREV_26 again:
read32 0xfaafcff8 -> 0x600422d5
For all of them wl driver is using 0x2 reject bit:
write32(0xf98) <- 0x00010002
So it seems SSB 2.3 is the exception using another bit.

ath9k: set beacon related ps flags on bss_info change
Requesting beacon sync up to configure beacon timers properly
in hw, has be done after doing beacon config with default values.
Setting the flags in beacon config is causing the device to not
enter into network sleep on idle state.

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
