patch 'net/mlx5: fix MPRQ WQE size assertion' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/26/22. 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

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/85d9e45c32ee046eea992a0cf57d1c8efcc5a144

Thanks.

Kevin

Subject: [PATCH] net/mlx5: fix MPRQ WQE size assertion

[ upstream commit 728b6447e766fc0aaf59e888635d62d54e77a528 ]

Preparation of the stride size and the number of strides for
Multi-Packet RQ was updated recently to accommodate the hardware
limitation about minimum WQE size. The wrong assertion was
introduced to ensure this limitation is met. Assert that the
configured WQE size is not less than the minimum supported size.

Fixes: 34776af600df ("net/mlx5: fix MPRQ stride devargs adjustment")
