   4 Subject: [PATCH] ath10k: handle tdls peer events
   5
   6 Handle tdls peer events from the target. TDLS events for the peer
   7 could be discover, teardown, etc. As of now, adding the logic to
   8 handle tdls teardown events alone.
   9
  10 Teardown due to peer traffic indication(PTR) timeout is one such
  11 teardown event from the target.
  12
  13 Tested this change on QCA9888 with 10.4-3.5.1-00018 fw version.
