Subject: [PATCH net-next v2 00/12] virtnet_net: prepare for af-xdp

This patch set prepares for supporting af-xdp zerocopy.
There is no feature change in this patch set.
I just want to reduce the patch num of the final patch set,
so I split the patch set.

Thanks.

v2:
    1. Add five commits. That provides some helper for sq to support premapped
       mode. And the last one refactors distinguishing xmit types.

v1:
    1. resend for the new net-next merge window



Xuan Zhuo (12):
  virtio_net: independent directory
  virtio_net: move core structures to virtio_net.h
  virtio_net: add prefix virtnet to all struct inside virtio_net.h
  virtio_net: separate virtnet_rx_resize()
  virtio_net: separate virtnet_tx_resize()
  virtio_net: separate receive_mergeable
  virtio_net: separate receive_buf
  virtio_ring: introduce vring_need_unmap_buffer
  virtio_ring: introduce dma map api for page
  virtio_ring: introduce virtqueue_dma_map_sg_attrs
  virtio_ring: virtqueue_set_dma_premapped() support to disable
  virtio_net: refactor the xmit type
