[dpdk-stable] patch 'net/mlx5: fix order of items in NEON scatter' has been queued to LTS release 18.11.3

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to LTS release 18.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/26/19. 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/e986e60c7526b2b01e0864aca0b7eb539d7b7101

Thanks.

Kevin Traynor

Subject: [PATCH] net/mlx5: fix order of items in NEON scatter

[ upstream commit 0d51a5ec26ccca4582f4762854ac3b28208c4a04 ]

Previous patch added handling of metadata for multi-segment packet.
Function txq_scatter_v in file mlx5_rxtx_vec_neon.h was updated
incorrectly, items were inserted into WQE in wrong order.

This patch fixes the issue, inserting items into WQE correctly.

Fixes: 7f4019d370f6 ("net/mlx5: fix Tx metadata for multi-segment packet")
