Realtek 8852BE support

Realtek 8852BE support

[Charles Piekarski]

Dear Sir or Madam,

I would like to kindly ask for information if Realtek 8852BE Wi-Fi 6 
module is supported or will be supported by the Linux kernel. 
Regrettably, the module does not work under Ubuntu 22.04.1 and 22.10, at 
least out of the box, and I was unable to find any useful information to 
get it working in a safe way (with Secure Boot enabled).

Kind regards,
Charles Piekarski

Related to this, we have a crystal ball service which tries to predict
merge window and release schedules:

https://phb-crystal-ball.sipsolutions.net/

I should add a link to that in our wiki, I don't think it's mentioned
anywhere.

Charles,

You can get that driver by doing a 'git clone 
https://github.com/lwfinger/rtw89.git' and building it following the 
instructions in file README.md from that repo. If you are using Ubuntu, pay 
particular attention to the last paragraph as the distro has not included the 
firmware for RTW8852BE, even though that firmware has been in the official 
linux-firmware repo since October.
