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.

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? -Toke
