description:
  The 3-port switch gigabit ethernet subsystem provides ethernet packet
  communication and can be configured as an ethernet switch. It provides the
  gigabit media independent interface (GMII),reduced gigabit media
  independent interface (RGMII), reduced media independent interface (RMII),
  the management data input output (MDIO) for physical layer device (PHY)
  management.
