Perhaps it might be useful to start with a higher default (even something like 1<<8) as that would allow adjusting up/down single stations, without having to adjust all stations and listening to new additions to adjust them quickly etc? Theoretically this doesn't really matter, but from a practical POV it may be easier to leave them all at the default and just adjust the ones that need adjustment for some reason.
ieee80211_sta_register_airtime
Do we really need this? We already have at least TX status with airtime, for ieee80211_sta_tx_notify() and friends, and the station pointer in that context, so couldn't we piggy-back on this? At least WMM-AC already requires the driver to provide this. johannes
