Hello, here is my proposal how to add U-APSD client support to mac80211. I also included example driver implementation for wl1251. Patches should be ready now. v6: o store max SP length value in unconverted format and shift is just before use (suggested by Johannes) v5: o rename IEEE80211_HW_UAPSD to IEEE80211_HW_SUPPORTS_UAPSD o U-APSD queue and max SP length configuration debugfs interface (requested by Jason) o dynamic ps support for U-APSD o by default enable U-APSD in all queues o back to RFC state due to new code o add a warning if both PS_NULLFUNC_STACK and U-APSD are enabled o wl1251: set qos null data template o more defines to ieee80211.h v4: o use IEEE80211_WMM_IE_STA_QOSINFO prefix in ieee80211.h (Jason Young) o fix VI and BK qosinfo values in ieee80211.h (Jason Young) o add IEEE80211_WMM_IE_AP_QOSINFO_UAPSD v3: o remove unnecessary debugfs interface, people can recompile mac80211 in case they want to try enable more queues o add max SP length defines to ieee80211.h o removed unnecessary code comments v2: o remove cfg80211 changes o rename IEEE80211_QOS_IE to IEEE80211_WMM_IE_STA in ieee80211.h --- Kalle Valo (7): mac80211: add U-APSD client support mac80211: add debugfs interface for U-APSD queue configuration mac80211: create tx handler for dynamic ps mac80211: check uapsd state for dynamic power save ieee80211: add struct ieee80211_hdr_qos wl1251: create qos null data template wl1251: add U-APSD support drivers/net/wireless/wl12xx/wl1251_main.c | 37 +++++++++- include/linux/ieee80211.h | 28 ++++++++ include/net/mac80211.h | 7 ++ net/mac80211/cfg.c | 7 ++ net/mac80211/debugfs.c | 94 ++++++++++++++++++++++++++ net/mac80211/ieee80211_i.h | 27 +++++++ net/mac80211/main.c | 6 ++ net/mac80211/mlme.c | 31 ++++++++ net/mac80211/scan.c | 18 +++++ net/mac80211/tx.c | 106 ++++++++++++++++++----------- net/mac80211/util.c | 2 + net/mac80211/work.c | 12 +++ 12 files changed, 326 insertions(+), 49 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
