Hi Russell

Marvell mv88e6390X switches are like this is a well. There is a PCS
for SGMII and 1000Base-X, and a second one for 10G. And it dynamically
swaps between them depending on the port mode, the so called cmode.

So a generic solution is required, and please take your time to build
one.

I'm happy to test when you are ready.

Thanks for working on this,
