101d1f7fbf ath6kl: remove redundant null pointer check on send_pkt
The check for send_pkt being NULL is redundant before the call
to htc_reclaim_txctrl_buf, therefore it should be removed. This was
detected by static analysis by cppcheck.

3b282bc609 wil6210: Add proper handling for invalid frames on Rx
On Rx, when invalid frame is received and dropped,
reaping of next frames from Rx ring is stopped.

This stops NAPI polling and re-enables the Rx interrupt.

However, in cases where no more frames received,
interrupt will not be triggered and rest of Rx frames
will not be processed.

Skip bad frames and continue to reap Rx packets when
such frames are encountered, and add statistics for
such frames for debug.

ab4e3db043 ath10k: optimize ce_lock on post rx buffer processing
After processing received packets from copy engine, host will allocate
new buffer and queue them back to copy engine ring for further
packet reception. On post rx processing path, skb allocation and
dma mapping are unnecessarily handled within ce_lock. This is affecting
peak throughput and also causing more CPU consumption. Optimize this
by acquiring ce_lock only when accessing copy engine ring and moving
skb allocation out of ce_lock.

In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak
throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak
throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps
(71% CPU load). Similarly ~40Mbps improvement is observed in downlink
path.

ath10k is using Native WiFi mode as default mode for both of
Tx and Rx path, but it could be changed when driver registers
with a module parameter for specific purpose such as mesh.

The Rx decap mode sent to firmware during WMI initialization should
use the same mode that driver configured at its registration stage
in case of using raw mode, so that host driver receives MAC frame
header containing necessary fields such as QoS and Mesh Control
and uses them in right way to make data traffic work.

621a5f7ad9 debugfs: Pass bool pointer to debugfs_create_bool()
Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument,
when all it needs is a boolean pointer.

It would be better to update this API to make it accept 'bool *'
instead, as that will make it more consistent and often more convenient.
Over that bool takes just a byte.

That required updates to all user sites as well, in the same commit
updating the API. regmap core was also using
debugfs_{read|write}_file_bool(), directly and variable types were
updated for that to be bool as well.

44acedb00b ath: use PRI value given by spec for fixed PRI
PRI value is used as divider when DFS detector analyzes candidate
radar pulses.
If PRI deviation is big from its origin PRI, DFS detector could miss
valid radar reports since HW often misses detecting radar pulses and
causes long interval value of pulses.

For instance from practical results, if runtime PRI is calculated as
1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
the modular remainder will be 1409 and the delta between the remainder
and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
As a result this radar report will be ignored even though it's valid.

By using spec defined PRI for fixed PRI, we can correct this error.

e904cf6fe2 ath9k_htc: introduce support for different fw versions
Current kernel support only one fw name with theoretically only one
fw version located in “firmware/htc_[9271|7010].fw”. Which is ok so far we
have only one fw version (1.3). After we realised new fw 1.4, we faced
compatibility problem which was decided to solve by firmware name and
location:
- new firmware is located now in
	firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw
- old version 1.3 should be on old place, so old kernel have no issues
	with it.
- new kernels including this patch should be able to try different
	supported (min..max) fw version.
- new kernel should be able to support old fw location too. At least for
	now.

At same time this patch will add new module option which should allow user
to play with development  fw version without replacing stable one. If user
will set “ath9k_htc use_dev_fw=1” module will try to find
firmware/ath9k_htc/htc_[9271|7010]-1.dev.0.fw first and if it fails, use
stable version: for example...1.4.0.fw.

634349bae0 ath10k: move hw_scan worker queuing
The remain_on_channel callback needs different
timeout. Calling ieee80211_queue_work() with a
shorter delay after calling it with a longer delay
will not change the timer. This caused the
offchannel timeout worker to not trigger in time
and caused the device to stay on channel longer
then expected. This could cause some problems and
was be easily reproduced with `iw offchannel`
command.

b6c7bafa7d ath10k: implement mesh support
Add support for mesh to ath10k.  We simply use an AP virtual interface
in the firmware in order to enable beaconing without TSF adoption, and
use the raw (802.11) transmit mode.

Due to firmware limitations, the firmware must operate in raw
(non-native 802.11) mode.  As this is configured at firmware init time,
a new "rawmode" modparam is added, and mesh interfaces are available
only if rawmode=true.  The firmware must advertise support for rawmode;
tested successfully with firmware 10.2.4.70.6-2.

When the module is loaded with (newly implemented) modparam rawmode=1, it
will enable operating an open mesh STA via something like the following:

    ip link set wlan0 down
    iw dev wlan0 set type mp
    ip link set wlan0 up
    iw dev wlan0 set freq 5745 80 5775
    iw dev wlan0 mesh join mesh-vht

6ccea107eb ath10k: print invalid mcs reported in rx descriptor
Sometimes hardware reports invalid mcs index in rx descriptor
when operating in VHT80 mode and all packets with invalid mcs
will be eventually dropped in mac80211. This issue is observerd during
testing on QCA99X0 chipsets.

This patch adds a warn message for dumping the rx desc info which helps
in analysing the issue when invalid mcs is received.

The VHT STS CAP shall be reported by firmware to host, like in case of
QCA99x0. For QCA6174 hw family this isn't set for some reason.
So for this particular chips, let's assume it has the ability to
support VHT NDP in up to 4 STSs (which is true by the way).

Change the published beamformee STS cap accordingly to 3 or to what
the firmware reports.

Assumption so far, it suppose to be the num_rf_chains-1, was
completely wrong.

7b7da0a021 ath10k: drop probe responses when too many are queued
In a noisy environment, when multiple interfaces are created,
the management tx descriptors are fully occupied by the probe
responses from all the interfaces. This prevents a new station
from a successful association.

Fix this by limiting the probe responses when the specified
threshold limit is reached.
