The advantage of having two ethernets in parallel and say using the "EQL"
driver on it is redundancy. You can get 20Mbit out of the setup (if all
your hosts have it), and if for some reason the link is broken you drop
to 10Mbit as opposed to losing the entire network.

I'm not sure if the EQL driver will handle muliple hosts connected up,
but this type of redundancy isn't anything new either...
