I am working on a custom board with two LAN8720A on board. I can see both eth0 and eth1 are brought up. I can ping local computer for both ports. However, I cannot ping the remote ip address, nor set the port as dhcp. Am I missing anything? If I disable eth1 and just use eth0 port, I do not have this problem.

I am sure that I have my dns set. How come I do not have this problem when I disable the eth1?
