s/rectriction/restriction/

Is there any product name or code name you could put something in the
subject line to connect this to the hardware?

Maybe you could also add the relevant details to the PCI ID database
here?  https://pci-ids.ucw.cz/read/PC/8086  This will help lspci show
the correct name.
