This adds an API to mac80211 to handle scheduling of TXQs. The interface between driver and mac80211 for TXQ handling is changed by adding two new functions: ieee80211_next_txq(), which will return the next TXQ to schedule in the current round-robin rotation, and ieee80211_return_txq(), which the driver uses to indicate that it has finished scheduling a TXQ (which will then be put back in the scheduling rotation if it isn't empty). The driver must call ieee80211_txq_schedule_start() at the start of each scheduling session, and ieee80211_txq_schedule_end() at the end. The API then guarantees that the same TXQ is not returned twice in the same session (so a driver can loop on ieee80211_next_txq() without worrying about breaking the loop. Usage of the new API is optional, so drivers can be ported one at a time. In this patch, the actual scheduling performed by mac80211 is simple round-robin, but a subsequent commit adds airtime fairness awareness to the scheduler.
