[PATCH net-next 06/12] ixgbe: Use C45 mdiobus accessors

Michael Walle michael at walle.cc

From: Andrew Lunn <andrew at lunn.ch>

When performing a C45 bus transaction, make use of the c45 variants of
the bus read/write helpers. The ability to pass a special register
value is being removed to clean up the mdio bus driver API.
