Whichever address that will be, ok :)
Though, actually, scanning is not just a STA feature is it? APs will
sometimes want to do a quick background scan too, I think.

Not really, unless you can implement a TSF adoption per local MAC
address. I guess you could turn off powersave and do the backoff
algorithm a bit out of spec and get by with just one timer too.
