This is a mempool handler that is useful for pipelining apps, where the mempool cache doesn't really work - example, where we have one core doing rx (and alloc), and another core doing Tx (and return). In such a case, the mempool ring simply cycles through all the mbufs, resulting in a LLC miss on every mbuf allocated when the number of mbufs is large. A stack (LIFO) recycles buffers more effectively in this case. Signed-off-by: David Hunt <david.hunt@intel.com> Acked-by: Olivier Matz <olivier.matz@6wind.com>
