From 0a5cc49750b89717ad02abf132aa119743c0e5d4 Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Thu, 16 Mar 2017 16:16:11 +0530 Subject: [PATCH] mwifiex: send fewer channels to scan while connected Application triggers periodic background scans when device is connected. We will scan less number of channels per scan command so that data traffic won't get affected.
