[dpdk-dev] [PATCH 0/4] eth_ring: perf test and usability improvements

[Bruce Richardson <bruce.richardson@intel.com>]

This patchset makes it easier to create ring pmd instances from code, by
providing a simple ring->ethdev wrapper function and also ensuring that
any created rings are ready for use immediately, without having to call
configure and rx/tx queue setup.

This set also contains a set of unit tests to compare the performance of
basic ring operations against the same operations via the ring ethdev.
This shows how the perf penalty can be significant for small bursts, but
is much less so for larger bursts of 32 packets.

Bruce Richardson (4):
  ring: enhance rte_eth_from_rings
  rte_ring: store memzone pointer inside ring
  ring: add rte_eth_from_ring function
  test: Add perf test for ring pmd
