I got this card from a computer tower I disassembled :
https://www.tp-link.com/us/home-networking/pci-adapter/archer-t4e/

It is not supported at the moment. You can also check here
https://marc.info/?l=openbsd-misc&m=178654718862573&w=2
but I'm not sure whether it appears in the dmesg, unless it's:
vendor "Realtek", unknown product 0x8812 (class network subclass
miscellaneous, rev 0x01) at pci6 dev 0 function 0 not configured

I can post it somewhere and take in charge the transportation fees.
Is anyone interested ?
