Now that I figured out where the ethernet addresses come from

on NetFPGA-10G, assign one to the interface by default in a very
similar way.

* If we do not have an ether address set, initialize to the same

* Oh and we keep the way of setting it from a string as they do.
* It's an amazing way to hide it.
* XXX-BZ If NetFPGA gets their own OUI we should fix this.
