From d5556e87610e45e586b1bdf6653920b543083653 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Fri, 4 Dec 2015 06:13:02 -0800 Subject: [PATCH] mwifiex: parse adhoc start/join result Even if ADHOC start or join attempt is failed, these commands are returned with success status by firmware. Actual connection result is provided inside command response. This patch parses the adhoc connection result and resets connection state variables if connection is not successful.
