On my machine, i40e will not startup if using VFIO.

The normal Linux driver works correctly. Firmware has been updated to the latest version.
Like my earlier experience with fm10k, I suspect that Intel never tests i40e with IOMMU,
and only tested with igb_uio.

I found the issue. It was a problem with older version of Xen DOM0 patches
which were still outstanding in the internal development package.
