Are you trying to run the ROACH1 on 1 GbE? ROACH1 is not reliable on 1 GbE. You have to force it to be 100 Mbps. This can be done by using an unmanaged non-gigabit switch (or hub), a managed switch that can force its port for the ROACH1 to be 100 Mbsp only. For direct connect, you'll have to use "mii-tool" on the server.
Another thing that always gets me is MTU. I don't think the ROACH1 u-boot supports jumbo frames, so you'll have to run the server with MTU==1500 to netboot ROACH1.
