Hi,

FYI, your patch has been queued to stable release 22.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/14/25. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/5b625cccee6408f9c998eb367bd7fc1935c05c98

Thanks.

Luca Boccassi

Subject: [PATCH] common/mlx5: remove useless constants

[ upstream commit 5f961fec22ff6903f2a11ffdc5ffef9c8c50cb5b ]

All these constants were unused since their introduction:

- MLX5_DRV_PROBE_AGAIN
- MLX5_NL_BUF_SIZE
- MLX5DV_FLOW_TABLE_TYPE_RDMA_RX
- IB_QPT_RAW_PACKET

Fixes: ad435d320473 ("common/mlx5: add bus-agnostic layer")
Fixes: ccdcba53a3f4 ("net/mlx5: use Netlink to add/remove MAC addresses")
Fixes: 03e1f7f760d8 ("net/mlx5: create flow matcher object on Windows")
Fixes: 358fbb018310 ("net/mlx5: support multi-packet Rx queue on Windows")
