> Feed a tap device with IFF_NAPI from vhost-net with netdev_max_backlog
> set to 8, in the three ways vhost-net passes packets to tun: batches of

> that excess packets are dropped and counted, that the queue keeps
> draining and that every buffer comes back.
>
> The wrapper loads vhost_net and, if it can reload it, also runs the
> zerocopy variant with experimental_zcopytx=1.
