   4 Subject: ath9k: Fix sequence numbers for PAE frames
   5

   8 commit 6c8afef551fef87a3bf24f8a74c69a7f2f72fc82 upstream.
   9
  10 Currently, PAE frames are not assigned proper sequence numbers.
  11 Since sending PAE frames as part of aggregates breaks
  12 crupto with several APs, they are sent as normal MPDUs.
  13 Fix the seqeuence number issue by updating the frame with the
  14 internal sequence number.
