Subject: [PATCH 4.9 033/164] rtlwifi: rtl8821ae: setup 8812ae RFE according to device type
4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Larry Finger <Larry.Finger@...inger.net>
commit 46cfa2148e7371c537efff1a1c693e58f523089d upstream.
Current channel switch implementation sets 8812ae RFE reg value assuming
that device always has type 2.
Extend possible RFE types set and write corresponding reg values.
