Sure, that's ok I suppose. FWIW, if it makes the implementation a lot
simpler, adding it in mac80211 would be acceptable, but I'm not
convinced that CONF_PS is the right hook for it, since mac80211
throughout assumes CONF_PS will automatically wake up for beacons etc.,
and changing that would imho exponentially increase the already high
complexity of the powersaving implementation.
