Hi Heiner
Some of the PHYs embedded in Marvell switches have an OUI, but no
product ID. We work around this brokenness by trapping the reads to
the ID registers in the MDIO bus controller driver and inserting the
switch product ID. The Marvell PHY driver then recognises these IDs
and does the right thing.
Maybe you can do something similar here?
Andrew
