Neither.

Very weird. Can you please enable verbose debugging and also add a few
printks to various lines of the code in ieee80211_tx_h_multicast_ps_buf
and ieee80211_tx_h_unicast_ps_buf? Both ought to be fine as far as I can
tell and the STA scanning shouldn't be in powersave mode either so this
is a bit strange.
