I was working on an customised iMX6 board with two ethernet hubs.One ethernet is detecting as eth0 and was working fine.The second was an POE ethernet of chipset LAN7500.When I try to config this ethernet it was throwing an error like
eth1: error fetching interface information: Device not found
When I go to the following path cd /etc/udev/rules.d/70-
persistent-net.rules I was able to see the eth1 name for that interface.
Now,I am not able to understand what is the conflict here I was facing.
