FWIW

I have the same issue on a Lenovo T14 gen2 laptop with built-in ax210
card, and sold as Wifi-6E compliant.

The exact patch you mention causes the issue, so it seems my bios does
not return the correct values either.

I recompiled the kernel with all those cmd_allow_xxx bitmaps set to ~0
and 6Ghz works fine.
