[b: Um - sorry: I was referring to the network interfaces on the SS-5's system

One is an MII, the other is a BPP.

The MII requires a special adapter which happens to convert to AUI :).

You can only use one port on any given interface.

Now, if you have a be and the onboard le, you might be able to multiplex
through them at 10BaseT.  Maybe.  Some kind soul will no doubt say, "No,
Greywolf is Wrong, don't listen to him," which is fine, but I thought we
supported some sort of multiple-interface multiplexing
