This patchset rebased Yuanhan's virtio1.1 prototype [1] to the
current master branch of dpdk-next-virtio tree. It also contains
Jens' fixes, my fixes and optimizations.

After sending each RFC patchset to the mailing list, I'll also
collect them to my github repo [2] to give everyone a repo where
can find the latest working code of virtio1.1 prototype.

Best regards,
