| 14 | The 3-port switch gigabit ethernet subsystem provides ethernet packet |
| 15 | communication and can be configured as an ethernet switch. It provides the |
| 16 | gigabit media independent interface (GMII),reduced gigabit media |
| 17 | independent interface (RGMII), reduced media independent interface (RMII), |
| 18 | the management data input output (MDIO) for physical layer device (PHY) |
| 19 | management. |
