Linux 6.2 with 8822BU overrides RTL88x2BU module

[ogasser]

The Linux kernel 6.2 has (finally) added support for Realtek 8822BU. Unfortunately, this newly added in-tree module has a lower networking performance, at least on my system: 30 Mbps with 8822BU compared to 100 Mpbs (which is the maximum of my ISP contract) with RTL88x2BU.

After I added the following lines to /etc/modprobe.d/blacklist.conf Linux again loads the more performant RTL88x2BU module:

blacklist rtw88_core
blacklist rtw88_8822b
blacklist rtw88_usb
blacklist rtw88_8822bu

Maybe this should be added to the main README file @RinCat , in case other users are stumbling across this issue as well?

This warning already in the README for 10 months.
I don't know if we want to blacklist rtw88_core and rtw88_usb, since other devices may use them.

Yep, you are right, blacklisting rtw88_8822bu is enough and more specific!

I somehow missed the entry in the README, maybe I was searching for "Linux 6.2". It might be useful to mention that explicitly, as it has found its way into the mainline kernel with this release.
