I did test it enough to bring up a link but I needed this patch.
The patch fixes an incorrect assumption in original DPDK use of
VFIO, it just isn't visible on normal IOMMU hardware.

The real goal was to be able to use per-rxq interrupts but didn't
get that far along (because of time and other application issues).
