Patch needs to be rebased to target v18.11 (in map file), and indeed new APIs
(rte_flow_conv) needs to be experimental.

And needs to remove deprecation notice in this patchset.
Also do you think does make sense to announce this change in release notes?

Apart from above, any volunteer for reviewing actual implementation?
