Hi Viacheslav - these are new features, not a bugfixes. Are the
stable at dpdk.org tags intentional?

From
http://doc.dpdk.org/guides/contributing/stable.html#what-changes-should-be-backported

Features should not be backported to stable releases. It may be
acceptable, in limited cases, to back port features for the LTS release
where:

    There is a justifiable use case (for example a new PMD).
    The change is non-invasive.
    The work of preparing the backport is done by the proposer.
    There is support within the community.
