c639a708SPranavi Somisettydescription:
c639a708SPranavi Somisetty  The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
c639a708SPranavi Somisetty  Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
c639a708SPranavi Somisetty  ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
c639a708SPranavi Somisetty  This core can be used in all three modes of operation(10/100/1000 Mb/s).
c639a708SPranavi Somisetty  The Management Data Input/Output (MDIO) interface is used to configure the
c639a708SPranavi Somisetty  speed of operation. This core can switch dynamically between the three
c639a708SPranavi Somisetty  different speed modes by configuring the converter register through mdio write.
c639a708SPranavi Somisetty  The core cannot function without an external phy connected to it.
