Here is the consolidated series of mac80211, ath9k and ath10k changes for moving TXQ scheduling and airtime fairness into mac80211 and support airtime fairness. Three main APIs are defined for TXQ scheduling. - ieee80211_next_txq - ieee80211_return_txq - ieee80211_txq_may_transmit and two APIs for synchronization when the driver wants to iterate through all TXQs. - ieee80211_txq_schedule_start - ieee80211_txq_schedule_end The earlier discussions: https://patchwork.kernel.org/project/linux-wireless/list/?series=&submitter=&state=*&q=TXQ+scheduling&archive=both&delegate= -Rajkumar v2: - replaced driver specific airtime default by multiplier - fixed tab intent - fixed author and commit log v3: - fixed checkpatch warnings and kbuild bot errors. few of over 80 char warnings are left. v4: - Folded Louie's airtime counter reset change - rebased the series on top of mac80211 tree. Kan Yan (1): ath10k: reporting estimated tx airtime for fairness Toke Høiland-Jørgensen (5): mac80211: Add TXQ scheduling API cfg80211: Add airtime statistics and settings mac80211: Add airtime accounting and scheduling to TXQs ath9k: Switch to mac80211 TXQ scheduling and airtime APIs ath10k: migrate to mac80211 txq scheduling drivers/net/wireless/ath/ath10k/core.c | 2 - drivers/net/wireless/ath/ath10k/core.h | 8 +- drivers/net/wireless/ath/ath10k/htc.h | 1 - drivers/net/wireless/ath/ath10k/htt_rx.c | 9 ++ drivers/net/wireless/ath/ath10k/mac.c | 155 +++++++++++------- drivers/net/wireless/ath/ath10k/txrx.c | 4 + drivers/net/wireless/ath/ath9k/ath9k.h | 14 -- drivers/net/wireless/ath/ath9k/debug.c | 3 - drivers/net/wireless/ath/ath9k/debug.h | 8 - drivers/net/wireless/ath/ath9k/debug_sta.c | 70 --------- drivers/net/wireless/ath/ath9k/init.c | 3 +- drivers/net/wireless/ath/ath9k/recv.c | 9 +- drivers/net/wireless/ath/ath9k/xmit.c | 244 +++++++++-------------------- include/net/cfg80211.h | 10 +- include/net/mac80211.h | 121 +++++++++++++- include/uapi/linux/nl80211.h | 15 ++ net/mac80211/agg-tx.c | 2 +- net/mac80211/cfg.c | 3 + net/mac80211/debugfs.c | 3 + net/mac80211/debugfs_sta.c | 68 +++++++- net/mac80211/driver-ops.h | 9 ++ net/mac80211/ieee80211_i.h | 11 ++ net/mac80211/main.c | 9 ++ net/mac80211/sta_info.c | 46 +++++- net/mac80211/sta_info.h | 13 ++ net/mac80211/status.c | 6 + net/mac80211/tx.c | 140 ++++++++++++++++- net/wireless/nl80211.c | 30 ++++ 28 files changed, 662 insertions(+), 354 deletions(-)
