[PATCH vhost 0/6] virtio_net: rx enable premapped mode by default

[Xuan Zhuo <xuanzhuo@linux.alibaba.com>]

Actually, for the virtio drivers, we can enable premapped mode whatever
the value of use_dma_api. Because we provide the virtio dma apis.
So the driver can enable premapped mode unconditionally.

This patch set makes the big mode of virtio-net to support premapped mode.
And enable premapped mode for rx by default.

Please review.

Thanks.

  virtio_net: replace private by pp struct inside page
