patch 'net/mlx5: fix Rx split segment counter type' has been queued to stable release 25.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 25.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/27/26. 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/d7f9c47b846c186f68b2a5608f48f87891c74672

Thanks.

Kevin

Subject: [PATCH] net/mlx5: fix Rx split segment counter type

[ upstream commit 8653248a59fe10b007ccf543d287415e4b3c763e ]

In the API, rx_nseg and max_nseg are uint16_t.
In mlx5, MLX5_MAX_RXQ_NSEG is 32.
So there is no reason to have rxseg_n as uint32_t.
Reduce the fields to uint16_t and move them to avoid struct holes.

Fixes: 9f209b59c8b0 ("net/mlx5: support Rx buffer split description")
Fixes: 572c9d4bda08 ("net/mlx5: fix shared Rx queue segment configuration match")
