If we could use the phydev in the struct net_device, we could write a
generic function for {get|set}_link_ksettings. It's a good idea.

But I've quickly looked and a lot of ethernet driver use the private
structure to store the phydev. If the ethernet driver may use the
struct net_device for phydev, do you know why so many drivers use
the private structure ?

If everybody agree, I can send a new version with a generic {get|set}_link_ksettings
and a update of fec to use the phydev store in the structure net_device.

Philippe
