The patch appears to work, so waiting for the release of kernel 5.15.64 would be the easiest approach. It ought to be released fairly soon.
I can confirm that it will work when patching the kernel yourself: See AX211 Fails to Start on a range of kernels/firmwares (5.18.9, latest) - #11 by Rhys-Hussain. But it would seem easier to install the kernel-latest-qubes-vm-5.19 and use it for sys-net.
5.15.64 was released today and the AX210 now works on my system. I’m certain many others, who don’t want to use the latest-kernel, will be pleased. Thanks!
5.18 has EOL (kernel.org)
