FWIW defconfig does *not* enable most of the ThunderX drivers (most
importantly, PCI and networking will be missing).

I've just built the v4.13 tag with the appropriate drivers added and
booted it on a different ThunderX box - the net core throws some
warnings from __dev_xdp_attached() but it gets to userspace OK for me.
