Hi,
just to confirm that applying this patch fixes DPDK on my system at
least.
>From the discussion, I understood that this was a "compilation problem",
but in practice it manifests itself as compile working ok but your app
won't work with ports bound to vfio-pci. So please apply some fix for
this soon.
Thanks for the work on this, all.
