[PATCH 4.11 037/197] rtlwifi: rtl8821ae: setup 8812ae RFE according to device type

From: Greg Kroah-Hartman
Date: Tue May 23 2017 - 18:29:48 EST

4.11-stable review patch. If anyone has any objections, please let me know.

------------------

From: Larry Finger <Larry.Finger@xxxxxxxxxxxx>

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.
