I don't see any advantages, looks like just need some e.g callbacks in this
case.
Thanks
IUC callbacks pretty much destroy the code cache locality advantages,

This patch implements basic batched processing of tx virtqueue by
prefetching desc indices and updating used ring in a batch. For
non-zerocopy case, vq->heads were used for storing the prefetched
indices and updating used ring. It is also a requirement for doing
more batching on top. For zerocopy c
