529 * doesn't seem to be a dedicated event for that. So the
530 * only way left to do this would be to read tim_bitmap
531 * during SWBA.
532 *
533 * We could probably try using tim_bitmap from SWBA to tell
534 * mac80211 which stations are asleep and which are not. The
535 * problem here is calling mac80211 functions so many times
536 * could take too long and make us miss the time to submit
537 * the beacon to the target.
538 *
539 * So as a workaround we try to extend the TIM IE if there
540 * is unicast buffered for stations with aid > 7 and fill it
541 * in ourselves.
