There is a simple alternative for applications with a single mbuf pool to avoid
accessing m->pool.
We could add a global variable pointing to the single mbuf pool.
It would be NULL by default.
It would be set by rte_pktmbuf_pool_create() on first invocation, and reset
back to NULL on following

I propose
+Cc techboard
We need benchmark numbers in order to take a decision.
Please all, prepare some arguments and numbers so we can discuss
the mbuf layout in the next techboard meeting.

Thomas,
Adding my thoughts to the already detailed feedback on this important patch...
The first cache line is not inherently "hotter" than the second. The hotness
