A PS Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mb/s Ethernet
interface (see the following figure), which connects to TI DP83867IRPAP U134 Ethernet
RGMII PHY before being routed to a vertical dual-stacked RJ45 Ethernet connector J307
(lower receptacle). The RGMII Ethernet PHY is boot strapped to PHY address (0x02) and Auto Negotiation is set to Enable.
The following figure shows the dual Ethernet topology.
