Hello,
here is my proposal how to add U-APSD client support to mac80211. I
also included example driver implementation for wl1251.
Please comment. Also I would like to get comments how U-APSD needs to
be implemented in different hardware.
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
