The PS-side Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mb/s Ethernet interface, shown in the following figure, which connects to a TI DP83867IRPAP Ethernet RGMII PHY before being routed to an RJ45 Ethernet connector. The RGMII Ethernet PHY is boot strapped to PHY address 5'b01100 (0x0C) and Auto Negotiation set to Enable. Communication with the device is covered in the TI DP83867 RGMII PHY data sheet on the Texas Instruments website.
