From: Aniket Nagarnaik <[email protected]> Current TDLS implementation always includes ht/vht information in tdls setup confirm frame which causes teardown by legacy peer station after TDLS handshake. We will inclue ht/vht capabilities in tdls setup confirm frame only if peer station supports it to fix this problem.
