459 *
460 * We could probably try using tim_bitmap from SWBA to tell
461 * mac80211 which stations are asleep and which are not. The
462 * problem here is calling mac80211 functions so many times
463 * could take too long and make us miss the time to submit
464 * the beacon to the target.
465 *
466 * So as a workaround we try to extend the TIM IE if there
467 * is unicast buffered for stations with aid > 7 and fill it
