TX99 support enables Specific Absorption Rate (SAR) testing.
SAR is the unit of measurement for the amount of radio frequency(RF)
absorbed by the body when using a wireless device. The RF
exposure limits used are expressed in the terms of SAR, which is a
measure of the electric and magnetic field strength and power density
for transmitters operating at frequencies from 300 kHz to 100 GHz.
Regulatory bodies around the world require that wireless device
be evaluated to meet the RF exposure limits set forth in the
governmental SAR regulations.
In the examples below, for more bit rate options see the iw TX bitrate
setting documentation:
http://wireless.kernel.org/en/users/Documentation/iw#Modifying_transmit_bitrates
Example usage:
iw phy phy0 interface add moni0 type monitor
ip link set dev moni0 up
iw dev moni0 set channel 36 HT40+
iw set bitrates mcs-5 4

John W. Linville says:
====================
Regarding the Bluetooth bits, Gustavo says:
"The big work here is from Marcel and Johan. They did a lot of work
in the L2CAP, HCI and MGMT layers. The most important ones are the
addition of a new MGMT command to enable/disable LE advertisement
and the introduction of the HCI user channel to allow applications
to get directly and exclusive access to Bluetooth devices."
As to the ath10k bits, Kalle says:
"Bartosz dropped support for qca98xx hw1.0 hardware from ath10k, it's
just too much to support it. Michal added support for the new firmware
interface. Marek fixed WEP in AP and IBSS mode. Rest of the changes are
minor fixes or cleanups."
And also:
"Major changes are:
* throughput improvements including aligning the RX frames correctly and
optimising HTT layer (Michal)
* remove qca98xx hw1.0 support (Bartosz)
* add support for firmware version 999.999.0.636 (Michal)
* firmware htt statistics support (Kalle)
* fix WEP in AP and IBSS mode (Marek)
* fix a mutex unlock balance in debugfs file (Shafi)
And of course there's a lot of smaller fixes and cleanup."
For the wl12xx bits, Luca says:
"Here are some patches intended for 3.13. Eliad is upstreaming a bunch
of patches that have been pending in the internal tree. Mostly bugfixes
and other small improvements."
Along with that...
Arend and friends bring us a batch of brcmfmac updates, Larry Finger
offers some rtlwifi refactoring, and Sujith sends the usual batch of
ath9k updates. As usual, there are a number of other small updates
from a variety of players as well.

The conflicts are of two varieties:
1) Conflicts with Joe Perches's 'extern' removal from header file
function declarations. Usually it's an argument signature change
or a function being added/removed. The resolutions are trivial.
2) Some overlapping changes in qmi_wwan.c and be.h, one commit adds

When a packet is passed from mac80211 to the driver with the
IEEE80211_TX_CTL_PS_RESPONSE flag set, it bypasses the normal driver
internal queueing and goes directly to the UAPSD queue.
When that happens, packets that are part of a BlockAck session still
need to be tracked as such inside the driver, otherwise it will create
discrepancies in the receiver BA reorder window, causing traffic stalls.
This only happens in AP mode with powersave-enabled clients.

Fast antenna diversity is required only for single chain
chips and the diversity initialization is done in the
per-family board setup routines. Enabling of diversity
should be done based on the calibrated EEPROM/OTP data,
doing it for all chips is incorrect.
Remove the code that sets the fast_div bit for all cards, since
the documentation for the AR_PHY_CCK_DETECT register says:

* Disable SW PeakDetect calibration when RTT calibration is not enabled.

* Update RTT table according to the saved value.
* Write RTT back after modifying SW RTT table.

All QCA chips have the ability to parse the CF Parameter Set
IE in beacons. If the IE is malformed in the beacons from some
APs [1], the HW locks up. In AP mode, a beacon stuck would happen
and in client mode, a disconnection usually is the result.
To fix this issue, set the AR_PCU_MISC_MODE2_CFP_IGNORE to ignore
the CFP IE in beacons - this is applicable for all chips. For
AP mode, if this issue happens, the NAV is also corrupted and has
to be reset - this will be done in a subsequent patch.
