ACS in 5G channels for STA connected in 5G non DFS channel can result
SAP starting on DFS channel. Making MCC on DFS channel. This is
leading to FW panic if STA tries to roam during SAP is
detecting radar.
Avoid SAP starting on DFS channel if STA connected on 5G non DFS
Remove DFS channels from scan list before acs, if MCC is disllowed.
So, that DFS channel is not selectecd after acs.

When stop_bss from HDD is received when a SAP channel change request
is currently in progress and channel change response is not yet
received from the FW, the stop_bss would clear the SAP session and
when channel change response is received, we try to start BSS again.
The CSR roam state is also set to JOINING in this case.
As part of start BSS, we queue set key command to SME active command
list. Since the session has been cleared, eWNI_SME_SETCONTEXT_RSP
sent to lim would not be processed in CSR state JOINING leading to set
key command stuck in the active command list.
Do not restart BSS after channel change response if stop BSS is in
progress. Also handle eWNI_SME_SETCONTEXT_RSP and clear the command
queue in CSR Joining state.

When the channel list provided from hostapd contains both
2.4Ghz and 5Ghz channels and channel width is 40Mhz, scan
happens on all the 2.4Ghz and 5Ghz channels and ACS algo
runs on all the channels to find the best channel for
starting SAP in 40Mhz. If a 2.4Ghz is selected, an OBSS
scan happens on all the 2.4Ghz channels to check if there
is any legacy BSS present on any overlapping channel. If
any BSS is found, channel width fallbacks to 20Mhz and
SAP gets started in 20Mhz bw instead of 40Mhz. This is
generally the case with 2.4Ghz whereas there is no such
issue in 5Ghz channels.
Avoid 2.4Ghz channels for starting SAP in 40Mhz bw by
assigning max weight to all the 2.4Ghz channels if 5Ghz
channels are also present in the channel list provided
from hostapd.

In sap_update_rssi_bsscount, bss count for channels is
incremented based on offset only and does not consider
if channel on which scan result is received and the
offset channel belong to same band. This could result
in incorrect increment of bss count for some channels
when channels from both bands are present.
Fix is to increment bss count based on channel offset
only if both channels belong to same band and also
choose channel with lower bss count among the channels
having least weight.

When channel list contains all channels from channel 1 to channel
165 and ch width is 80MHz, the channel to be selected as part of
ACS algorithm should be a 5GHz channel as 2.4GHz channels does not
support 80MHz but 2.4GHz channel gets selected with channel
width as 40MHz. Similarly when ch width is 160Mhz, the 160Mhz bonding
can be made only by 36-64 and 100-128 channels but 2.4Ghz channel or
some other 5Ghz channel gets selected as a result of ACS algorithm.
Assign max weight to all the 2.4GHz channels in 80Mhz and to all 2.4 Ghz
channels and 5Ghz channels not in the range 36-64 and 100-128 in 160 Mhz
so that only a valid channel is selected after the ACS algorithm is

BSS count is 0 and RSSI is max. As the channel with lowest weight

selected.
