The var was supposed to be protected by data_lock
but it wasn't so in all instances. It's actually
not necessary to have a spinlock protected
num_peers so drop it.
All instances of num_peers are already within
conf_mutex sections so use that.

This prevents warning spamming if peer creation

Add mem_val debugfs file for dumping the firmware (target) memory and also for
writing to the memory. The firmware memory is accessed through one file which
uses position of the file as the firmware memory address. For example, with dd
use skip parameter for the address.
Beucase target memory width is 32 bits it's strongly recommended to use
blocksize divisable with 4 when using this interface. For example, when using
dd use bs=4 to set the block size to 4 and remember to divide both count and
skip values with four.
To read 4 kB chunk from address 0x400000:
dd if=mem_value bs=4 count=1024 skip=1048576 | xxd -g1
To write value 0x01020304 to address 0x400400:
echo 0x01020304 | xxd -r | dd of=mem_value bs=4 seek=1048832
To read 4 KB chunk of memory and then write back after edit:
dd if=mem_value of=tmp.bin bs=4 count=1024 skip=1048576
emacs tmp.bin
dd if=tmp.bin of=mem_value bs=4 count=1024 seek=1048576

Debugfs files reg_addr and reg_val are used for reading and writing to the
firmware (target) registers. reg_addr contains the address to be accessed,
which also needs to be set first, and reg_value is when used for reading and
writing the actual value in ASCII.
To read a value from the firmware register 0x100000:
# echo 0x100000 > reg_addr
# cat reg_value
0x00100000:0x000002d3
To write value 0x2400 to address 0x100000:
# echo 0x100000 > reg_addr
# echo 0x2400 > reg_value

ath10k_tx_wep_key_work() acquires conf_mutex, so
cancelling it when conf_mutex is already taken
in ath10k_remove_interface() is incorrect, so
move it outside the lock.

When static keys are used in shared WEP, when a
station is associated, message 3 is sent with an
encrypted payload. But, for subsequent
authentications that are triggered without a
deauth, the auth frame is decrypted by the HW.
To handle this, check if the WEP keys have already
been set for the peer and if so, mark the
frame as decrypted. This scenario can happen
when a station changes its default TX key and initiates
a new authentication sequence.

With P2P concurrency requested hw roc duration
time can be very small. Some firmware revisions
refuse scan requests with too small channel dwell
time.
This prevents messages like, e.g. with connected
STA vif and performing P2P Find:
ath10k_pci 0000:00:05.0: failed to switch to channel for roc scan
ieee80211 phy3: failed to start next HW ROC (-110)

New firmware revisions don't need peer creation
when doing offchannel tx. Earlier revisions would
queue and never release frames without a peer.
This prevent new firmware revisions from stopping
replenishing wmi-htc tx credits and improves
reliability of offchannel tx which would sometimes
silently fail.

It appears it takes more than just setting the
hardware's chainmask to make things work well. Without
this patch, a vdev would only use 1x1 rates when chainmask
was set to 0x3.
Setting the 'nss' (number of spatial streams) on the vdev
helps the firmware's rate-control algorithm work properly.

We had introduced delay main work logic to avoid processing
interrupts when Rx pending packet count reaches high threshold.
interrupt processing is restarted later when packet count
reduces lower threashold. This helped to reduce unnecessary
overhead and improve throughput for SD and PCIe chipsets.
As there are no interrupts for USB, we will skip this logic for
USB chipsets.

When the driver has sent a join iovar to the firmware it waits
for the events to report result of the connection. However, the
wpa_supplicant will request a .disconnect() after a timeout. So
upon calling .disconnect() the interface state may still be
CONNECTING. Clear the CONNECTING bit as well.

In the Makefile for this driver, the wrong Kconfig option is used
to trigger the compilation of the object file. This leads to the
driver only being included into the kernel when both CONFIG_RTL8821AE
and CONFIG_RTL8192AE are set to "y".

In four of the rtlwifi drivers, the Makefile contains superfluous
statements indicating the compilation of the driver as an LKM
regardless of the corresponding Kconfig option.
If the corresponding option is set to 'y', the build system will then
see the object file in obj-m and obj-y, which leads to a compilation
as a built-in only. Even though this leads to the desired behavior,
the unconditional appearance in obj-m is confusing for someone reading
the Makefile.
This patch removes the superfluous Makefile statements.

The patch fixes a static checker warning:

brcmf_cfg80211_set_pmksa()
warn: can 'pmkid_len' be negative?
The answer to the question above is likely no so changing its
type to unsigned is sufficient.

When the device wakes up due to netdetect, we need to query different
things from the firmware than when it wakes up with a normal WoWLAN.
To make this easier, separate the netdetect wake up handling from the
rest. For now, we don't send netdetect as a wake up reason, treating
it as a non-wireless wake up.

When another vif is also running during a channel switch, we need to
use a session protection when we move to the new channel, so that we
don't miss the beacons. Without this, sometimes the other vif
repeatedly gets time exactly when we should be hearing the beacons,
preventing channel switch from completing. Adding a session
protection that lasts from the moment the channel changes until 2
TBTTs later, ensures that we will hear the beacons on the destination
channel.
