[PATCH 00/19] virtio_ring in order support

[Jason Wang <jasowang@redhat.com>]

Hello all:

This sereis tries to implement the VIRTIO_F_IN_ORDER to
virtio_ring. This is done by introducing virtqueue ops so we can
implement separate helpers for different virtqueue layout/features
then the in-order were implmeented on top.

Tests shows 5% imporvemnt in RX PPS with KVM guest + testpmd on the
host.

Please review.

Thanks
