As was stated before, to improve lwIP's integration with hardware regarding
zero copy, we need people to work with us that have specific needs. Fun
fortunately, retiree haven't been too many people doing this, lately.
Regarding the implementation hiding, I don't think that it's too hard to just
override pbuf_alloc() and pbuf_free() to get what you suggested. The only
limitation (that I'm aware of and hopefully will be fixing it soon), is that
PBUF_REF types don't fully work with pbuf_header().
