mdio: Add register definitions for MDIO (clause 45)
IEEE 802.3 clause 45 specifies the MDIO interface and registers for use in 10G and other PHYs, similar to the MII management interface. PHYs may have up to 32 MMDs corresponding to different sub-layers and functions, each with up to 65536 registers. These are addressed by PRTAD (similar to the MII PHY address) and DEVAD. Define a mapping for specifying PRTAD and DEVAD through the existing MII ioctls. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>
