Works for me ;P First of all, networking cards on ThunderX are PCI Virtual Functions so you need to bring them up using iovctl. If you watched the youtube demo you should have seen that at first there are no interfaces in ifconfig and then I do iovctl and they appear. Secondly, EFI that runs on the board needs to pass the correct DTB to the kernel (it has to have PCIB, BGX, MDIO, PHYs nodes and they need to be in the correct order [MDIO needs to attach before BGX]).
