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.
