Setting of WMM-PS (UAPSD) parameters from supplicant in STA mode

Just one more question.
As I see uapsd_queues parameter is not a part of mac80211 debugfs.c So should we be adding that?

Why dont you use mac80211 debugfs? We can uapsd_queues parameter and choose individual uapsd status for each AC.
