> The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
> Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
> Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
> This core can be used in all three modes of operation(10/100/1000 Mb/s).
> The Management Data Input/Output (MDIO) interface is used to configure the
> Speed of operation. This core can switch dynamically between the three
> Different speed modes by configuring the conveter register through mdio write.

> Using MAC MDIO bus we can access both the converter and the external PHY.

Series applied, thanks.
