Hi Chris

You say SERDES here, but in DT you have rgmii-id?

Can you run 1000Base-X over these links? If you can, it is probably
worth chatting to Russell King about using inband-signalling, and what
is needed to make it work without having back to back SFPs. If i
remember correctly, Russell has said not much is actually needed.
