I don't think we need new pktmbuf_init().
We just need to update it, so both pktmbuf_init() and detach() setup
buf_addr, buf_len (and priv_size) to exactly the same values.
If they don't do that, it means that you can't use attach/detach with
mempools created with pktmbuf_init() any more.

BTW, another thing that I just realised:
examples/ipv4_multicast and examples/ip_fragmentation/ -
both create a pool of mbufs with elem_size < 2K and don't populate mempool's private area -
so mbp_priv->mbuf_data_room_size == 0, for them. 

So that code in detach():

 +	mbp_priv = rte_mempool_get_priv(mp);
 +	m->priv_size = mp->elt_size - RTE_PKTMBUF_HEADROOM -
 +		mbp_priv->mbuf_data_room_size -
 +		sizeof(struct rte_mbuf);


Would break both these samples.
I suppose we need to handle situation when mp->elt_size < RTE_PKTMBUF_HEADROOM + sizeof(struct rte_mbuf),
(and probably also when mbuf_data_room_size == 0) correctly.
