Like Ben I don't really understand where your  problem  is.  We  have
many  boards  with  multiple Ethernet Interfaces; for example, we see
boards with up to 4 x TSEC and up to 2 x  EEPRO100  controllers.  And
there is never more than a single "active" device.

We don't need any such code there. Why would you need it?

Best regards,

Wolfgang Denk
