This patch adds the xMDIO interface support in the mvmdio driver. This
interface is used in Ethernet controllers on Marvell 370, 7k and 8k (as
of now). The xSMI interface supported by this driver complies with the
IEEE 802.3 clause 45 (while the SMI interface complies with the clause
22). The xSMI interface is used by 10GbE devices.

Hi Antoine

I've only take a quick look, but i don't see anywhere you look at the
register address and see if it has MII_ADDR_C45 to determine if a C45
transaction should be done, or a C22. The MDIO bus can have a mix of
C45 and C22 devices on it, and you need to use the correct transaction
type depending on the target device/address.
