> Subject: [PATCH v6 1/2] mbuf: support attaching external buffer to mbuf
>
> This patch introduces a new way of attaching an external buffer to a mbuf.
>
> Attaching an external buffer is quite similar to mbuf indirection in
> replacing buffer addresses and length of a mbuf, but a few differences:
> - When an indirect mbuf is attached, refcnt of the direct mbuf would be
> 2 as long as the direct mbuf itself isn't freed after the attachment.
> In such cases, the buffer area of a direct mbuf must be read-only. But
> external buffer has its own refcnt and it starts from 1. Unless
> multiple mbufs are attached to a mbuf having an external buffer, the
> external buffer is writable.
> - There's no need to allocate buffer from a mempool. Any buffer can be
> attached with appropriate free callback.
> - Smaller metadata is required to maintain shared data such as refcnt.
