From 2c3da961268ff7f4a6c958fee081c58aef2e5c1d Mon Sep 17 00:00:00 2001 From: Aniket Nagarnaik Date: Fri, 18 Sep 2015 06:32:08 -0700 Subject: mwifiex: don't always include ht/vht info in tdls confirm frame 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.
