Should be quite easy to do. All based vendor/device buses have tables mapping
IDs to drivers (/usr/src/sys/dev/usb/usbdevs in this case).

Then the specific driver does some further magic to make sure it's matching
the right device (in that case, look at if_udav.c, the udav_lookup macro
and the list udav_devs).

If you set up your ethernet adapter that way, and it works, it's probably
worth sending us a detailed patch, preferably to tech@openbsd.org...
