6.3.1 Interface Selection
U-Boot provides support for multiple Ethernet interfaces for transferring files from a file server.
This is accomplished using the environment variables: “ethprime”, “ethact” and “ethrotate”.
The following table indicates the assignment of the Ethernet interfaces to the AMC ports or to
the GbE front panel connectors depending on the active “sconf” base configuration.
