 447  * FIXME
 448  *
 449  * We don't report to mac80211 sleep state of connected
 450  * stations. Due to this mac80211 can't fill in TIM IE
 451  * correctly.
 452  *
 453  * I know of no way of getting nullfunc frames that contain
 454  * sleep transition from connected stations - these do not
 455  * seem to be sent from the target to the host. There also
 456  * doesn't seem to be a dedicated event for that. So the
 457  * only way left to do this would be to read tim_bitmap
 458  * during SWBA.
 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
 468  * in ourselves.
