 984  * FIXME
 985  *
 986  * We don't report to mac80211 sleep state of connected
 987  * stations. Due to this mac80211 can't fill in TIM IE
 988  * correctly.
 989  *
 990  * I know of no way of getting nullfunc frames that contain
 991  * sleep transition from connected stations - these do not
 992  * seem to be sent from the target to the host. There also
 993  * doesn't seem to be a dedicated event for that. So the
 994  * only way left to do this would be to read tim_bitmap
 995  * during SWBA.
 996  *
 997  * We could probably try using tim_bitmap from SWBA to tell
 998  * mac80211 which stations are asleep and which are not. The
 999  * problem here is calling mac80211 functions so many times
1000  * could take too long and make us miss the time to submit
1001  * the beacon to the target.
1002  *
1003  * So as a workaround we try to extend the TIM IE if there
1004  * is unicast buffered for stations with aid > 7 and fill it
1005  * in ourselves.
