When the device is set to boot through the Ethernet mode, the ROM Code configures PHY, NAVSS, and the CPSW. These initial configurations, as well as the interface mode (RMII, RGMII), are determined by querying the BOOTMODE pins, see Section 4.3.13, Ethernet Boot Device Configuration, and the boot parameter table for the Ethernet boot, see Section 4.4.7, Ethernet Boot Parameter Table.
The queue manager is setup to route the packets to queues polled by the ROM Code.
