Hey
I got myself a Surface Pro 7 and thought it had a supported AX201 wifi chip in
it but after some looking around in the source I couldn’t find the device ID in
there so I tried myself to add it to pcidevs and pcidevs.h.
I also added the pci_products to if_iwx.c and pcidevs_data.h. I got it to show
up in dmesg. But I get “iwx0: unsupported AX201 adapter". I think Im in a bit
of deep water here and my knowledge is to low for it. Im wondering if someone
else has gotten this AX1650 card to work?
Here is pcidump from the machine:
