Hi All:
This is a new version to support VIRTIO_F_RING_RESET. The feautre
extends the basic facility to allow the driver to reset a virtqueue.
This main motivation is to support the reset function of the queue of the

Please review.

For MRG_RX, we require that all payloads are placed in the position
specified by offset in each receive buffer. So we can also use
build_skb() without wasting memory. Because we can reuse the
"offset" parts that are not used.
