qca6174 with wmi-tlv firmware uses offloaded
beaconing scheme (i.e. templates). This requires a
little different approach when implementing CSA.

Add missing code to update CS count and report CSA
completion to mac80211. Without it channel switch
was never finished.

To avoid races during interface teardown data_lock
has been used to protect is_up and is_started so
they can be compared against before scheduling
count down work.

The current SKID length configuration causes firmware
to reject peer creation for not able to allocate
AST entries for peers. This issue is observed when
least significant 3 bytes are used ramdomly to create
client MAC addresses.

AST table SKID length configuration is increased to
maximum value to fix this issue.

Having lower number of copy engine entries for target to host

qca6174 WLAN.RM.2.0-00073 firmware uses full rx
reordering offload and delivers Rx via a new HTT
event. The event however is incorrectly generated
in firmware and becomes overly long (with trailing
garbage). This was hitting defined CE buffer limit
that was programmed to the device and caused
device to crash upon busier Rx traffic.

Increasing the CE buffer limit for HTT Rx pipe to
2KBytes seems to be enough to workaround this
problem.

For the current %8s sscanf we require cmd to be 9 chars long

than reduce the %8s specifier to %7s as cppcheck recommends).

The MCI configuration values are assigned
in ath9k_hw_btcoex_init_mci() which are used
by the MCI reset routine. When initializing
