 440  * FIXME
 441  *
 442  * We don't report to mac80211 sleep state of connected
 443  * stations. Due to this mac80211 can't fill in TIM IE
 444  * correctly.
 445  *
 446  * I know of no way of getting nullfunc frames that contain
 447  * sleep transition from connected stations - these do not
 448  * seem to be sent from the target to the host. There also
 449  * doesn't seem to be a dedicated event for that. So the
 450  * only way left to do this would be to read tim_bitmap
 451  * during SWBA.
 452  *
 453  * We could probably try using tim_bitmap from SWBA to tell
 454  * mac80211 which stations are asleep and which are not. The
 455  * problem here is calling mac80211 functions so many times
 456  * could take too long and make us miss the time to submit
 457  * the beacon to the target.
 458  *
 459  * So as a workaround we try to extend the TIM IE if there
 460  * is unicast buffered for stations with aid > 7 and fill it
 461  * in ourselves.
