Hi Andrew,

No, it doesn't seem to be necessary there - I haven't seen spontaneous
link-ups with the 88x3310 there. Even if we did, that would cause other
issues beyond a nusience link-up event, as the PHY selects the first
media that has link between copper and fiber (and both are present on
Macchiatobin platforms.)

If the fiber indicates link up, it would prevent a copper connection
being established.

phydev->sfp_bus being non-NULL?
