The three-port gigabit ethernet switch subsystem (GMAC_SW) provides ethernet packet communication and can be configured as an ethernet switch. It provides the reduced gigabit media independent interface (RGMII), and the management data input output (MDIO) for physical layer device (PHY) management.
Figure 26-207 shows the GMAC_SW subsystem overview.
