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

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.

Xuan Zhuo (6):
  virtio_ring: introduce dma map api for page
  virtio_ring: enable premapped mode whatever use_dma_api
  virtio_net: replace private by pp struct inside page
  virtio_net: big mode support premapped
  virtio_net: enable premapped by default
  virtio_net: rx remove premapped failover code
