From c1619fa7cc81439fa3a791e5462e161ccc5536e5 Mon Sep 17 00:00:00 2001
From: Jes Sorensen <Jes.Sorensen@redhat.com>
Date: Fri, 22 Jul 2016 13:17:36 -0400
Subject: [PATCH] rtl8xxxu: Implement rtl8188e_disable_rf()
This is partly guessware as there is no straight forward disable RF
routine in the vendor driver.
