When the ethernet PHY's compatible string is 'ethernet-phy-id0141.0cc2', it will be matched with the Marvell driver in Linux instead of the generic driver. They differ from reading the PHY register17.11 bit which is for 'Speed and Duplex Resolved' and the value 0 will clear phydev->link and stop the flow. To avoid getting stuck, change the constant return value in QEMU for the bit to 1 to keep the driver going.
