A PS Gigabit Ethernet MAC (GEM) implements a 10/100/1000 Mbps Ethernet interface
(see the figure in PMC MIO[49] and LPD_MIO[12:25]: GEM1 Ethernet), which connects to
TI DP83867IRPAP U198 Ethernet RGMII PHY before being routed to a vertical dual-stacked
RJ45 Ethernet connector J307 (upper receptacle). The RGMII Ethernet PHY is boot strapped
to PHY address (0x01) and Auto Negotiation is set to
Enable.
