hi
board is imx6ul-14x14-evk.
Does the board's dual ethernet support independent work?
Is it possible to choose one of the ethernets to work independently, or two ethernets to work at the same time?
Yes, it is possible to use the dual ethernet port independently as well as both the ethernets at the same time.
To use only a single Ethernet, we can change the device tree node and disable the ethernet which you don't want to use.
