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.
