commit b789e3fe7047296be0ccdbb7ceb0b58856053572 upstream.
RFE type4 is a new NIC which has one RF antenna shares with BT. RFE type4 HW is the same as RFE type2 but attaching antenna to aux antenna connector.
RFE type2 attach antenna to main antenna connector. Load the same parameter as RFE type2 when initializing NIC.

commit e109e3617e5d563b431a52e6e2f07f0fc65a93ae upstream.
Ping-Ke Shih answered[1] a question for a user about an rtl8821ce device that reported RFE 6, which the driver did not support. Ping-Ke suggested a possible fix, but the user never reported back.
A second user discovered the above thread and tested the proposed fix. Accordingly, I am pushing this change, even though I am not the author.
