First of all, I'm very sorry for being so late on review!

I didn't quite remember we have come an agreement on that. I think my
old concern still counts: how do you handle the combo like DPDK v17.11
and QEMU v2.7-2.9 (assume we take this patch in DPDK v17.11) ?

Note that it's not a trivial bug, it's a fatal bug that freezes QEMU,
IIRC.
