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

Polling TX statuses too frequently has two negative effects. First is
randomly peek CPU usage, causing overall system functioning delays.
Second bad effect is that device is not able to fill TX statuses in
H/W register on some workloads and we get lot of timeouts like below:
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_entry_txstatus_timeout: Warning - TX status timeout for entry 7 in queue 2
ieee80211 phy4: rt2800usb_txdone: Warning - Got TX status for an empty queue 2, dropping
This not only cause flood of messages in dmesg, but also bad throughput,
since rate scaling algorithm can not work optimally.
In the future, we should probably make polling interval be adjusted
automatically, but for now just increase values, this make mentioned
problems gone.

The regression was introduced in the following commit:
0967e01e8e
"ath5k: make use of the new rate control API"
ath5k_tx_frame_completed saves the intended per-rate retry counts before
they are cleared by ieee80211_tx_info_clear_status, however at this
point the information in info->status.rates is incomplete.
This causes significant throughput degradation and excessive packet loss
on links where high bit rates don't work properly.
Move the copy from bf->rates a few lines up to ensure that the saved
retry counts are updated, and that they are really cleared in
info->status.rates after the call to ieee80211_tx_info_clear_status.

Since we set IEEE80211_HW_QUEUE_CONTROL, we can let
mac80211 do the queue assignement and don't need to
override its decisions.
While reassiging the same values is harmless of course,
it triggered a WARNING when iwlwifi and mac80211 came
to different conclusions. This happened when mac80211 set
IEEE80211_TX_CTL_SEND_AFTER_DTIM, but didn't route the
packet to the cab_queue because no stations were asleep.
iwlwifi should not override mac80211's decicions for
offchannel packets and packets to be sent after DTIM,
but it should override mac80211's decision for AMPDUs
since we have a special queue for them. So for AMPDU,
we still override info->hw_queue by the AMPDU queue.
This avoids:

the rt2800_link_tuner function has been modified to
adjust VGC level for the RT5592 chipset.
On the RT5592 chipset, the VGC level must be adjusted
only if rssi is greater than -65. However the current
code adjusts the VGC value by 0x10 regardless of the
actual chipset if the rssi value is between -80 and
-65.

Just some minor conflicts between the wireless-next changes
and Joe Perches's "extern" removal from function prototypes
in header files.
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.

It was observed few times, the artificial max_scan limit we
are using mainly to detect FW hangs, can be not enough for
instance while being associated and during heavy traffic.
What we do if the FW won't return with scan results within
the max_time time is a scan abort.
This is especially visible with 10.X fw which in combination
with dual band HW (scanning 32 channels) can end up with
hw_scan close to 10 seconds.

There is also a new command - the channel inhibition command.
This command tells BT what channels to avoid in order to
minimise the interaction between BT and WiFi.
We can tell BT about 2 channels, primary and secondary.
BT will not tune to primary at all and will avoid secondary
as much as possible.
This also means that we need to track vifs that AP / GO.

When firmware restart happens, the timers are obviously reset and
the new firmware has no synchronisation with the AP as we program
timings to the pre-restart values. The firmware should attempt to
synchronise by itself, but in multi-channel scenarios this isn't
easy, particularly since it has to try to keep service quality up
for other MACs.
To make it more reliable, give each client MAC some time to catch
beacons when restarting or resuming. Service quality was impacted
anyway (or in resume doesn't really matter much.)

When RFKill cuts short a scan, mac80211 cancels the scan.
This is done by sending a host command to the firmware, but
this command was dropped because of RFKill. Flag this
command as "SEND_IN_RFKILL" to make sure it is sent to the
firmware. The firmware will send SCAN_COMPLETE_NOTIFICATION
which will trigger a call to ieee80211_scan_completed.
If the scan cannot be aborted, it is because the firmware
already finished the scan but we hadn't notified mac80211
at the time mac80211 decided to cancel the scan. By the time
we see the scan could not be aborted, mac80211 has been
notified already.
This patch fixes situations in which we didn't notify
mac80211 upon completion of the scan that was cut short
by RFkill.

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.

601216e "mwifiex: process RX packets in SDIO IRQ thread directly"
introduced a command timeout issue which can be reproduced easily on
an AM33xx platform using a test application written by Daniel Mack:
https://gist.github.com/zonque/6579314
mwifiex_main_process() is called from both the SDIO handler and
the workqueue. In case an interrupt occurs right after the
int_status check, but before updating the mwifiex_processing flag,
this interrupt gets lost, resulting in a command timeout and
consequently a card reset.
Let main_proc_lock protect both int_status and mwifiex_processing
flag. This fixes the interrupt lost issue.

Firmware IE containers can dynamically provide various information what
firmware supports. Also it can embed more than one image so updating firmware
is easy, user just needs to update one file in /lib/firmware/.
The firmware API 2 or higher will use the IE container format, the current API
1 will not use the new format but it still is supported for some time. FW API 2
files are named as firmware-2.bin (which contains both firmware and otp images)
and API 1 files are firmware.bin and otp.bin.

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.
