Hi Tom,
The following changes since commit 8d7f06bbbef16f172cd5e9c4923cdcebe16b8980:
I rebased on your master and built for BB Black. DHCP seems to work fine. MLO also now fits again.

Tom, this [1] is the patch that is breaking the evm. It doesn't affect BB Black because it uses an SMSC phy, where as this evm uses an AR8031/AR8033.
Is it possible the device tree [2] is wrong for the board? It lists 'phy-mode = "rgmii-txid";', so that means that with this patch the RX delay is now being disabled.
Any thoughts, Vladimir?
Thanks, -Joe

Thanks for tracking this down. I believe the DTS is right as it matches the kernel in this regard. That said, it's the Bone which has the schematic available and not the EVM so I can't point at that for further digging.
