Hi,

I retested the version from https://github.com/lwfinger/rtw88 on linux
5.10.16 - starting with the commits on Mar 9, 2021. It now seems to work
pretty fine even on 2.4 GHz / 40 MHz! Thanks to Realtek for their support!

Additional credit goes to Larry Finger, who thankfully provides this
additional source tree to make the progress of the driver accessible to
a lot more kernels than the actual one!

Thanks
Klaus
