Currently the driver includes all the DFS channels as part of scan
in the scan list, and thus not exclude the DFS channels in the first
scan for faster scan.
Fix is to check the ini, for first DFS channel scan, and then remove
the DFS channels from the scan list if the ini is enabled.

indicates this capability when underlying hardware
has RSSI reporting feature. Based on this capability
host will know if firmware sends SNR or RSSI. If no

rssi using a fixed offset of -96. If capability is
present host will directly use the rssi as it is.

Currently if the number of APs in the STA environment
are many, then the STA will receive many beacons, whose
beacon process path can take long time, in the kernel
work queue, hence the other processes have to wait
for them to complete, and may get timeout, if the
the time to process the beaocns is larger than their
process timeout.
Fix is to :-
1. Add rate limit to failure conditions of memory
not allocated
2. Make memory allocation in path of beacon process
atomic.

AP is configured to operate in Channel 100(HT80), and Zero Wait DFS
is enabled. Once PreCAC is complete on DFS Channels,inject radar in
Channel 100 and AP moves to another DFS channel 116 and beacons
immediately but station associated to AP still does a scan again.
When the station receives the Channel Switch Announcement from AP, it
dissociates from the AP and scans again.
Maximum Switch time Information Element can be used by the Station to
to know if the AP has done PreCAC on target channel. Maximum Switch Time
IE is part of AP's beacon and is the sum of CAC timeout on the target
channel and 1 beacon interval.
If PreCAC is done on target channel, the CAC timeout is zero and Maximum
Switch time IE is equal to 1 beacon interval. This element is sent to
Station along with Channel Switch Announcement. The Station receives the
maximum channel switch time element. If the value of maximum channel switch
time element is less then or equal to beacon interval, the station
associates with the AP seamlessly without dissociation. If the value of
the Maximum Channel Switch Time IE is greater than 1 beacon interval, then,
the Station has to dissociate from the AP since, ZeroCAC has not been done
by the AP.

Currently the driver calculates the nss score
based upon the max capability of the AP, and not the
hw_mde config which would be there after connection
for example, the driver calculates the score for a

11n AP in 1x1 mode, if a concurrent connection is
present, which affects throughput

in DBS or not, if yes then change the NSS to 1 instead of
2
