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. 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 | 50 +++++- 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, 644 insertions(+), 354 deletions(-)
