Currently, if Channel change is required via DCS then ACS
is triggered to select the best available channel . In case of
XR SAP optimization, SAP can not come on 2 GHz and frequencies
that can be shared by current SAP frequency on same MAC are
removed from scan list. As result of which frequencies
5/6 GHz in case of DBS and 5 GHz low/5 GHz high + 6 GHz based
on which 5 GHz range is shared with 2 GHz will be disacrded from scan
list. In short Scan can not be triggered on freqeuncies of same MAC
on which SAP is up and can not come in MCC. So, if any other device
mode is up on 2 GHz on other MAC turning on SAP on other MAC can
cause MCC in case of SBS and DBS HW which is not preferred.
Fix is to start SAP on random 6 GHz channel when case CSA is required
due to DCS in case SAP can't come up on 2 GHz and scan can not be
triggered for same MAC on which SAP is enabled i.e ACS optimization
is enabled for XR SAP.
