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

When we tried the below command at our end we saw netdev :wlan<x> was absent. Our driver registers with mac80211.
But when we use inbuilt chip on wlan0 which also registers with mac80211, it shows the complete directory struct up until params we need.
What configuration are we missing? I  understand this group is not for kernel related queries but any help here would be appreciated

It is part of mac80211 debugfs, for STA interface you can find it at "/sys/kernel/debug/ieee80211/phy0/netdev\:wlan0"
