The patch "mac80211: fix PS-poll response race" somehow broke broadcast buffering in a funny way. During normal operation - stations are awake - the firmware refused to transmit broadcast frames and reported P54_TX_PSM_CANCELLED. But everything worked as soon as one station entered PSM. The reason: The stack sets IEEE80211_TX_CTL_SEND_AFTER_DTIM for outgoing broadcast frames as soon as a station is marked as sleeping. This flag triggers a path which will reroute these frames into p54's "content after beacon" queue, which is designed to cope with the demands for psm. This patch restores the old behavior. IEEE80211_TX_CTL_CLEAR_PS_FILT will once again be used to signalize the firmware to ignore the ps canceling for certain frames.
