filtered).
Why should ieee80211_sta_set_tim() be called from complete_aggr() ?
I should probably add an extra check that tests for tid->buf_q being
empty - and some comments.
This handles a race condition that occurs if an A-MPDU completes (with
some pending frames) after the station entered PS and
ieee80211_sta_set_tim was not called because the buffer queue was empty.
