I see the idea, I guess, but but honestly I don't like the way this is
all mixed up between cfg80211 and mac80211.

I think more of this should be in cfg80211 (e.g. not sure why the
changes to ieee80211_change_iface, nothing there that cfg80211 couldn't
do; and generally would prefer to have the patch split), but since it
can never be perfect there (internal scans like in mac80211, etc.), I
guess it really also should come with a feature flag. That'd also make
the series more robust, with enabling the feature only in the last
commit.
