In net/mac80211/mlme.c function ieee80211_sta_tx_notify: If a null frame was acked, ieee80211_sta_reset_conn_monitor is called. This function sets probe_send_count to 0. After the call to ieee80211_sta_reset_conn_monitor, it is checked if probe_set_count is > 0. This means that ieee80211_queue_work will not be called even though the nullfunc was successful. The symptom of this error is that when using power save, it will take 500ms to enter power save again after a successfully acked null frame. What case will the check for 'probe_send_count > 0' cover?
