But you can't be sure where the mbuf came from.
It could be a receive on any vendors driver, or it could be from a private pool
that is  used for transmit, or anywhere.

Please reconsider the real nature here; the world is not testpmd, l2fwd, l3fwd etc.
These are the kind of optimizations that break real applications and cause 
more trouble than the benefit for one silly benchmark.
