 525  *
 526  * I know of no way of getting nullfunc frames that contain
 527  * sleep transition from connected stations - these do not
 528  * seem to be sent from the target to the host. There also
 529  * doesn't seem to be a dedicated event for that. So the
 530  * only way left to do this would be to read tim_bitmap
 531  * during SWBA.
 532  *
 533  * We could probably try using tim_bitmap from SWBA to tell
 534  * mac80211 which stations are asleep and which are not. The

 537  * the beacon to the target.
