From de651ce3d750c19a7b8b7cef22407ecc496619f4 Mon Sep 17 00:00:00 2001 From: Xinming Hu Date: Tue, 23 Feb 2016 05:16:16 -0800 Subject: [PATCH] mwifiex: add delay when tdls confirm frame is queued It is observed that driver may send the data packet to tdls peer before tdls peer receives tdls setup confirm frame. Similar race condition exists during tdls teardown procedure also. This patch adds 10 milliseconds delay to resolve the race.
