2.20.1
These commits can fix the problem of wifi not loading properly. At
least in my 5.10 kernel environment, the following error message is
reported:
rtw_8821ce 0000:01:00.0: rfe 6 isn't supported
rtw_8821ce 0000:01:00.0: failed to setup chip efuse info
rtw_8821ce 0000:01:00.0: failed to setup chip information
so I think that 5.10 need to merge these commits.
The patch 1/3 and patch 2/3 need to be merged synchronously, otherwise it
will cause OE and then kernel exception.
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.

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.

How does this meet the stable kernel rules?
This looks like new hardware support to me, right? What bugfix does
this resolve for 5.10 kernels?
And for newer support, why can you not just move to 5.15?
confused,

This is not in the original commit log at all. Shouldn't this be in the
0/3 email instead?
And yes, this hardware is not supported in the 5.10 kernel tree, please
move to 5.15 or newer and it will be fine.
