From a60809313b96c9489780944e6df45357b20d2ef5 Mon Sep 17 00:00:00 2001 From: Anilkumar Kolli Date: Fri, 27 Oct 2017 11:12:28 +0300 Subject: [PATCH] ath10k: block offchannel operations if TDLS session is active Do not allow off channel operations like scans/roc when there are active TDLS sessions. The Current firmware 10.4-3.5.1-00035 on QCA9888 does not supports any offchannel operations on active TDLS sessions, either driver needs to block the offchannel operation requests or should teardown the TDLS connection.
