If this patch is sent together with virtio-net + AF_XDP, I feel that this patch set will be too big. I can add the disable/enable function of tx/rx pair to virtio-net. But no one uses this function for now, so I put it on github. I'll include these patches for virtio-net using these new helpers in the next patch set.
