This may not be necessary, since this controller isn't CONFIG_NET_MULTI 
compatible, although it should be.  Yeah, I know you pointed this out 
already.  Sorry...

This type of configuration is not at all theoretical.  While it's hardly 
a shining example of hardware design, we have a board that uses both 
TSECs on an MPC8349 for high speed traffic, but we needed another 10/100 
interface for control purposes.  We put a cheap MAC/PHY chip on the 
local bus to meet this need.  It wasn't a DM9000, but it could have been.
