Hi Florian

The SERDES in the 6352 also look very similar to a standard MII PHYs.

Maybe at some point, we should look at the SERDES drivers we have
embedded in different MAC drivers, and see if we can pull them out,
maybe put them in drivers/net/phy. Any SERDES driver being used in
combination with phylink probably has the same API.
