 526  *
 527  * I know of no way of getting nullfunc frames that contain
 528  * sleep transition from connected stations - these do not
 529  * seem to be sent from the target to the host. There also
 530  * doesn't seem to be a dedicated event for that. So the
 531  * only way left to do this would be to read tim_bitmap
 532  * during SWBA.
 533  *
 534  * We could probably try using tim_bitmap from SWBA to tell
 535  * mac80211 which stations are asleep and which are not. The
 536  * problem here is calling mac80211 functions so many times
 537  * could take too long and make us miss the time to submit
 538  * the beacon to the target.
 539  *
 540  * So as a workaround we try to extend the TIM IE if there
