Nothing, its a bug. DPDK changed the API here with commit
9aaccf1abdb2894ec23870e1d2199a657f85850e but it never got changed in the
virtio_user pmd. You need to modify the pmd like the other call sites have been
in the above commit.
This is why those external pmds need to be merged into the dpdk tree.
