i.MX6 Ethernet not working, but acts like it is

We have a custom board that was copied from the sabresd board.  Ethernet appears to be working, the interface is created, but dhcp does not work.  After a few seconds, it assigns a strange default IP address, so using connman I set a static IP address to match our network.  I am unable to ping anything, but ifconfig tells me that there are no errors or dropped packets, and are a lot of received packets as well.


The ethernet section of the device tree is identical to the sabresd.dtsi file, so I don't think that it's that.  If I unplug the ethernet cable, it recognizes that it's unplugged, and when I plug it back in it sees that too.  The only thing that I can think of is that the first line says the supply phy was not found, using dummy regulator.  Do I need to set this somewhere?  Any thoughts on what might be wrong?  Thanks!
