546 * FIXME
547 *
548 * We don't report to mac80211 sleep state of connected
549 * stations. Due to this mac80211 can't fill in TIM IE
550 * correctly.
551 *
552 * I know of no way of getting nullfunc frames that contain
553 * sleep transition from connected stations - these do not
554 * seem to be sent from the target to the host. There also
555 * doesn't seem to be a dedicated event for that. So the
556 * only way left to do this would be to read tim_bitmap
557 * during SWBA.
558 *
559 * We could probably try using tim_bitmap from SWBA to tell
560 * mac80211 which stations are asleep and which are not. The
561 * problem here is calling mac80211 functions so many times
562 * could take too long and make us miss the time to submit
563 * the beacon to the target.
564 *
565 * So as a workaround we try to extend the TIM IE if there
566 * is unicast buffered for stations with aid > 7 and fill it
567 * in ourselves.
