[PATCH 0/5] XDP for virtio_net

[John Fastabend <john.fastabend@gmail.com>]

This implements virtio_net for the mergeable buffers and big_packet
modes. I tested this with vhost_net running on qemu and did not see
any issues.

There are some restrictions for XDP to be enabled (see patch 3) for
more details.

  1. LRO must be off
  2. MTU must be less than PAGE_SIZE
  3. queues must be available to dedicate to XDP
  4. num_bufs received in mergeable buffers must be 1
  5. big_packet mode must have all data on single page

Please review any comments/feedback welcome as always.

Thanks,
John
