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

It's great that you are working on this but
I'd like to see the actual use of this first.

I want to finish this work quickly. I don't have a particular preference for
whether to use a separate directory; as an engineer, I think it makes sense. I
don't want to keep dwelling on this issue. I also hope that as a maintainer, you
can help me complete this work as soon as possible. You should know that I have
been working on this for about three years now.

I can completely follow your suggestion regarding splitting the directory.
However, there will still be many patches, so I hope that these patches in this
patch set can be merged first.

   virtio_net: separate virtnet_rx_resize()
   virtio_net: separate virtnet_tx_resize()
   virtio_net: separate receive_mergeable
   virtio_net: separate receive_buf
   virtio_net: refactor the xmit type

I will try to compress the subsequent patch sets, hoping to reduce them to about 15.

Thanks.
