virtqueue ops were introduced in the hope that we'll have multiple implementations besides virtio_ring, but none have surfaced so far, and given that existing virtio ring is deployed in production we are likely stuck with it now, so this layer just adds complexity and overhead. Further, the need to pass vq twice to each call (as in dev->vq->vq_ops->kick(dev->vq) ) adds potential

The previous patch set had an error and one development branch's changes showed up twice, and two different change sets. So it was missing the bulk of the configuration work. This patch set fixes that.
