Bug#991297: rtw_8821ce does not work in debian 11

[Michele Bucca <michele.bucca@gmail.com>]

Package: firmware-realtek
Version 20210315-2

I'm testing debian bullseye and I've noticed that despite the firmware
of the wireless card Realtek RTL8821ce being added to the package, it
is still not working.

I downloaded the ISO debian-live-blsy-DI-rc2-amd64-xfce+nonfree.iso from

https://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/bullseye_di_rc2-live+nonfree/amd64/iso-hybrid/debian-live-blsy-DI-rc2-amd64-xfce+nonfree.iso

and when I boot the system the Wireless card is not detected by Network Manager.

if I type dmesg -l err in the terminal I get the following error message:

[    8.123230] rtw_8821ce 0000:03:00.0: rfe 2 isn't supported
[    8.123394] rtw_8821ce 0000:03:00.0: failed to setup chip efuse info
[    8.123396] rtw_8821ce 0000:03:00.0: failed to setup chip information

this problem does not exist in Ubuntu 21.04, when my wireless card is
detected out of the box and works fine.
