The ethernet ports not work

I create the image referencing [How-to Article] Get started with ROS on Yocto
I flash the image created above to EPC-R3720. It worked.
But ethernet ports on EPC-R3720 are not working.

How do I enable the ethernet ports?

I guess the board is the new one with a new version of ethernet phy. This BSP of ROS you use is based on the old one. Please check with our local region support team for professional support.
