[dpdk-dev] [PATCH v4 3/3] test/test/mempool_perf: support default mempool autotest

[Santosh Shukla]

Mempool_perf autotest currently does perf regression for:
 * nochache
 * cache

Introducing default_pool, mainly targeted for ext-mempool regression
test. Ext-mempool don't need 'cache' modes so only adding test-case
support for 'nocache' mode.

So to run ext-mempool perf regression, user has to set
RTE_MBUF_DEFAULT_MEMPOOL_OPS="<>"

There is chance of duplication  ie.. if user sets

RTE_MBUF_DEFAULT_MEMPOOL_OPS="ring_mp_mc" then regression
will happen twice for 'ring_mp_mc'
