This is the easiest case. When + * the station sends a PS-Poll or a uAPSD trigger frame, mac80211 + * will inform the driver of this with the @allow_buffered_frames + * callback; this callback is optional. mac80211 will then transmit + * the frames as usual and set the %IEEE80211_TX_CTL_POLL_RESPONSE + * on each frame.

The cause is that allowing frames to be + * transmitted to a certain station is out-of-band communication to + * the device.
