mac80211: Add TXQ scheduling API
This adds an API to mac80211 to handle scheduling of TXQs and changes the interface between driver and mac80211 for TXQ handling as follows: - The wake_tx_queue callback interface no longer includes the TXQ. Instead, the driver is expected to retrieve that from ieee80211_next_txq() - Two new mac80211 functions are added: ieee80211_next_txq() and ieee80211_schedule_txq(). The former returns the next TXQ that should be scheduled, and is how the driver gets a queue to pull packets from. The latter is called internally by mac80211 to start scheduling a queue, and the driver is supposed to call it to re-schedule the TXQ after it is finished pulling packets from it (unless the queue emptied). The ath9k and ath10k drivers are changed to use the new API. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
