Note In the following table, the first column shows the U-Boot environment variables that hold the MAC address of each network interface:
- 'ethaddr' holds the MAC address for ENET1, Linux probes this second and sees this as eth1
- 'eth1addr' holds the MAC address for ENET2, Linux probes this first and sees this as eth0
| U-Boot environment variable | Ethernet controller | Linux interface |
|---|---|---|
| ethaddr | ENET1 | eth1 |
| eth1addr | ENET2 | eth0 |
