Please just use one space between the type and var instead of two.

It's not necessary to use rte_mbuf_raw_alloc() here and
you forgot to initialize the allocated mbuf. I think you
can use rte_pktmbuf_alloc() directly as what I showed in
the example in my previous mail.

Typos:
first?
free_bufed?

If the last param is 0, then the third param could be NULL,
i.e. you don't need to define `len`.

Please use one space before '|' instead of two.
