If we're doing this on a per-driver basis, let's make it a proper
NL80211_EXT_FEATURE and expose it to userspace; that way users can at
least discover if it's supported on their device. I can send a patch
adding that...

Maybe we should untangle this from airtime_flags completely, since if we
just use the flags people could conceivably end up disabling it by
mistake, couldn't they?
