OK, I see now. I don't know of a way to tell if a device has multiple
ports just from the pci vendor/device id without maintaining some
sort of table.
Do these devices have multiple interfaces listed in their
/sys/devices/.../net diretory? If so, matching one of the listed
interfaces can just blacklist the whole device similar to blacklisting
by the device id.
