#define MII_INTERFACE "mii"
Obsolete interface that is implemented by some PHY's that support the MII management interface.
It has the same methods as the mii_management interface,
but does not pass along the PHY number.
To support low-level bitwise accesses via MDIO and MDC pins, the function serial_access can be used. It is recommended to leave this function unimplemented and let an instance of mii-management-bus convert the low-level bit operations to higher level read/write register calls.
