May be this is more of a mac80211 issue, currently while preparing
association request frame mac80211 uses imgd->uapsd_queues, so
need fetch that information from usespace up on interface addition viz.
a nl command? curently only NL command which has this info is ADD_STA
which is used in TDLS case.

Any ideas are appreciated.
