Firmware sends binary logs with WMIX_DBGLOG_EVENTID event. Create
a buffer which stores the latest logs and which can be copied from
fwlog debugfs file with cp command.
To save memory firmware log support is enabled only when CONFIG_ATH6KL_DEBUG
is enabled.

Probe Request reporting will be needed for P2P and WPS, but some
firmware builds do not seem to like this when P2P is not enabled.
Since we do not yet enable P2P, the safest option here is to just
remove this call for now and bring it back as a more dynamic version
once ath6kl starts advertising support for P2P.

P2P has special rules on when to include P2P IE(s) in Probe Response
frame based on the Probe Request frame. Handle P2P IE(s) separately
to follow these rules.

Patch "ath6kl: Fix buffer alignment for scatter-gather write" does
memmove for a length (scat_req->scat_list[i].len) which is not the
actual length of data that is suppossed to be moved. The right
lengh is packet->act_len + HTC_HDR_LENGTH. Using wrong length
for data move during buffer alignment causes system freeze after
the following WARN_ON and sometimes target assert.

Sometimes, the network manager is failing to connect to the AP due
to the below kernel crash message. The reason behind this,
after issuing the connect command to the chip, the chip is sending
disconnect event and then immediately one connect event to the host
in some random cases.
The host driver resets all states (including cfg80211 state machine)
when it receives disconnect event from the chip. But, still the host
driver reports the next received connect event to cfg80211, at that time
cfg80211 SME state would have been in IDLE state, which was causing
the below kernel crash.
Now, host driver's sme state machine is checked every time before
delivering connect event to cfg80211
