The boot process uses a default device configuration determined by either a lowest common
capability and/or the BOOT_MODE to load a boot image. The final device configuration
information is obtained from the boot image and can override the one used for the boot
process.

The PCIE-8120 card is configured for BOOTP on EMAC 2 on SERDES 2 (SGMII, 1Gbps).
