Is this really something we should do as a configuration option? Is the
default behavior to scan only the 6 GHz channels that are either PSC or
that have been determined to have a BSS based on neighbor report? And is
that somehow conditional on active vs. passive scanning?

I could understand having a need for a specific SCAN command that will
scan all 6 GHz channels passively, but it would seem more reasonable to
do that with a SCAN control interface command argument instead of a
configuration parameter that applies to all scan operations. Isn't it
way too slow to scan all non-PSC channels on the 6 GHz using a passive
scan for normal use?
