Currently, channel info event results are stored only if it is
received as part of SAP ACS scan. Channel info is used in
ACS algorithm to select best channel. There is a requirement to
reuse the STA's scan results for SAP to reduce the SAP bringup
time. So store the channel info event results received as part
of STA scan if WLAN_FEATURE_SAP_ACS_OPTIMIZE is enabled.

Currently if SAP is operating on 5GHz channel and if country change
happens to a world mode where SAP is not allowed on 5GHz channels so
SAP moves to a 2.4GHz channel and saves the current operating 5GHz
channel, now when again country change happens then SAP tries to
move to previous 5GHz channels, if SAP is not allowed on this 5GHz
channel in new country, SAP comes up on 2.4GHz channel.
Ideally SAP should come up on some other valid 5GHz channel instead
of 2.4GHz channel.
This scenario is possible for 6GHz channel as well.
To address above issue, add a fix to get first valid same band channel
if previous same band channel is not valid channel.

Per 11BE Spec, only 320 MHz support in 6 GHz is defined in EHT
PHY capabilities. Therefore when deciding max target supported
EHT bandwidth, 320 MHz support is first checked using target
advertised EHT phy caps. If 320 MHz is not supported, fall back
to VHT channel width supported, which includes 160 MHz and 80 MHz.

When SAP and GO home channels are in MCC in same band,
implement below requirement to avoid MCC:
1. SAP starts at first and GO starts later, then SAP will
force SCC to GO's home channel after GO starts up.
2. GO starts at first and SAP starts later, then SAP will
force SCC to GO's home channel during starting up.
3. SAP and GO SCC in same band, SAP changes channel to
the other channel in same band, GO will follow SAP and
move to SAP home channel.
4. SAP and GO SCC in same band, GO changes channel to the
other channel in same band, SAP will follow GO and move
to GO home channel.
And all the force SCC cases, if the target channel of force
SCC is not supported by the SAP or GO, then driver will
select other band's channel for the interface.

Based on the ini "sta_sap_scc_on_indoor_chan" the behavior of
STA+SAP in scc is as follows:
1. STA is on 2.4 GHz & SAP is on 2.4 GHz and SAP user configured
initial channel was on 5 GHz, then move SAP to 5 GHz initially
started channel
2. When STA + SAP are doing SCC on indoor only channel and
a) STA moves to 2.4 GHz -> then SAP moves to initialy started
channel
b) STA moves to another indoor only channel -> SAP follows
STA channel
c) STA moves to non-indoor, non-dfs channel -> SAP follows
STA channel.
d) STA moves to DFS channel -> SAP moves to 2.4 GHz channel
e) STA disconnects -> Move SAP to initially started channel
3. STA is on 2.4 GHz & SAP is on 5 GHz non-indoor, non-dfs channel
and STA moves to 5 GHz channel, then SAP should follow STA to 5 GHz
if SAP was initially started on 5 GHz channel. Else SAP restart
is not required and SAP will remain on the 2.4 GHz channel

If STA is active on 5G DFS channel, SAP CAC duration will

SAP fsm is still in SAP_STARTING state. In this state,

Fix by skip the CAC end event if CAC duration time is zero,
then the sap fsm will indicate CAC start/end event when

context to get concurrency status without checking Pre-CAC SAP's
