> improvements
> 
> 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
