It seems to be used to prefetch the mbuf in preparation for a free of an
mbuf.

But RTE_MBUF_PREFETCH_TO_FREE() currently does a prefetch for the
ffirst cache line in the mbuf,  but doesn't a free do a put to the mbuf's
mempool?

And isn't the mempool reference in the mbuf's second cache line?

mts.
