Afaik the mvme6100 does not have a configuration in libbsd. My recollection
(which could be wrong) is that there isn't a libbsd driver in the tree for
the NIC.

There was a table in Chris' EPICS slides about which bsps we thought needed
attention with notes on the drivers.

And the mvme2500 wasn't on the list. I think we may need an alias or some
documentation on this BSP.
