 * I know of no way of getting nullfunc frames that contain
 * sleep transition from connected stations - these do not
 * seem to be sent from the target to the host. There also
 * doesn't seem to be a dedicated event for that. So the
 * only way left to do this would be to read tim_bitmap
 * during SWBA.
 *
 * We could probably try using tim_bitmap from SWBA to tell
 * mac80211 which stations are asleep and which are not. The
 * problem here is calling mac80211 functions so many times
 * could take too long and make us miss the time to submit
 * the beacon to the target.
 *
 * So as a workaround we try to extend the TIM IE if there
 * is unicast buffered for stations with aid > 7 and fill it
 * in ourselves.
