FYI... Got ARM v7 variant of driver to work on Debian Buster 10 (Raspberry Pi OS) with RealTek 0bda:c811 Device.

Set the ARM (32 bit) configuration, then followed steps for DKMS build. It took quite a while, about 20 minutes or so to do a full compile. But worked on latest kernel. Linux 5.4.72-v7+ #1356 SMP Thu Oct 22 13:56:54 BST 2020 armv7l GNU/Linux.

Scan worked, and looks like association with access point worked as well. Got IP address via dhcpcd, so far so good. Shows both 2.4 GHz and 5.0 GHz bands, nice!

Still need to test a bit, but adapter showed under ifconfig once DKMS finished installation. Did get HALMAC warnings or errors initially in dmesg. But seemed to resolve its-self on 2nd HALMAC attempt. Maybe someone with more in depth known can explain what that means or qualifies?
