* Note(s) : (1) Supports Micrel KSZ8001BL PHY.
*
* (2) The MII interface port is assumed to be part of the host EMAC; consequently,
* reads from and writes to the PHY are made through the EMAC. The functions
* NetNIC_PhyRegRd() and NetNIC_PhyRegWr(), which are used to access the PHY, should
* be provided in the EMAC driver.
