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