I find this information extremely useful; thank you.

But the regulatory code did no such thing (so far as I can tell); that
iw list output doesn't at all match the iw reg get. Wireless-regdb 
doesn't define passive-scanning anywhere in the US regdom, and according
to iw list , there's in fact exactly zero 5GHz channels that I can
use in AP mode (all either disabled or passive scanning). Why?
