patch 'net/mlx5: fix flow dump for modify field' has been queued to stable release 22.11.3

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 22.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 08/11/23. 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://git.dpdk.org/dpdk-stable/log/?h=22.11-staging

This queued commit can be viewed at:
https://git.dpdk.org/dpdk-stable/commit/?h=22.11-staging&id=fa39f4c3582f719937e87e7b50490c5742e725dd

Thanks.

Subject: [PATCH] net/mlx5: fix flow dump for modify field
Cc: Xueming Li <xuemingl at nvidia.com>

[ upstream commit faecafc16f69c559323ec46ef110a771ce0bd7fb ]

When using other process to dump flow information, the modify field
information cannot be dumpped due to incorrect lcore value. Add loop
to get modify field information from all lcore to fix the issue.

Fixes: a7ac7fae4919 ("net/mlx5: enhance flow dump")
