Hi,

FYI, your patch has been queued to LTS release 18.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/29/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/kevintraynor/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable-queue/commit/397f9da5cbd4c093e69d8d6470a10aed20e85c2b

Thanks.

Kevin.

Subject: [PATCH] net/i40e: remove compiler barrier from NEON Rx

[ upstream commit f1f0f39806d97a9a4d74d47ce7fb04e9b4943e08 ]

As packet length extraction code was simplified,the ordering
was not necessary any more.[1]

2% performance gain was measured on Marvell ThunderX2.
4.3% performance gain was measured on Ampere eMAG80
