The reguluatory database is designed with 802.11 in mind, its database also provides enablement on frequency, not disablement. By default cfg80211 disallows everything except what is listed for the current regulatory domain being used. Your point about not being able to listen is a good one, and a patch to update the the US in consideration of part 15 rules would be appreciated. Keep in mind we have flags for such things: -Passive scan -No-IBSS We should probably rename no-ibss to no-beaconing though as that is the real meaning inention behind it.
