From 09f63ae65f907a7fadf7fcf408f80909cbf2af4b Mon Sep 17 00:00:00 2001 From: Avinash Patil Date: Wed, 28 Jan 2015 15:41:59 +0530 Subject: [PATCH] mwifiex: set wiphy params only once RTS threshold, fragmentation threshold are per device properties. Setting them on any interface would be reflected for all other interfaces as well. This patch removes unnesessary command download per interface.
