Hi Thomas, The latest version does not have ABI breakage issue. I have added the ABI verifier in my local patch verification setup. Series applied to dpdk-next-eventdev/master. Please pull this series from dpdk-next-eventdev/master. Thanks. I am marking this patch series as "Awaiting Upstream" in patchwork status to reflect the actual status.
