No, what I'm saying is that ifconfig would look exactly like it does now
for standard IP-over-EthII and for vlan id, and would be extended to handle
other configurations not currently supported like SNAP, or SNAP + VLAN.

It doesn't now, but it's only software.

That would be great, but this we should certainly move to -arch. Personally
I don't have any problems with gutting the network interfaces and moving
all MAC-layer protocols into netgraph nodes, but others might react violently.
With this group, you can never tell. ;^)
