In the U-Boot log, the names of the Ethernet interfaces are printed in the format <name>@<interface type>, for example, DPMAC3@xgmii. DPMAC is a DPAA2 object that identifies the physical interface.
Interface name is not fixed in LX2160ARDB, depending upon which interface is active, name will be assigned in TinyDistro as well as in Ubuntu distribution. Interface names can be checked using ls-listni command.
root@TinyDistro:~# ls-listni dprc.1/dpni.1 (interface: eth0, end point: dpmac.2) dprc.1/dpni.0 (interface: eth1, end point: dpmac.17)
