Do we plan on supporting both SNAP headers and IEEE headers? IP can use
both, some protocols can use only one or the other.

We need to set our min and max based on line speed and let the user
adjust
to some value between if they desire. 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.
