Min will probably be the same for both. Routing info only takes 30 octets, so we have to consider that as well. Also remember that all our data rides around in 802.2 packets so we have those headers to deal with as well. Eventually, our frame type code will deal with MTUs instead of ethernet/fddi/tokenring. The device will still determine the hard MTU but we have to have a way of supporting multiple MTUs per i/f. We don't really need to worry about that for now. If you like, you can do what the FDDI code did and just use all the ether_* stuff. /* Matthew N.
