patch 'net/mlx5: remove useless constants' has been queued to stable release 24.11.4

[Kevin Traynor <ktraynor@redhat.com>]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/26/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/ecf592265c91146f7140f637d262d94a37595fdf

Thanks.

Kevin

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

[ upstream commit 9d3788534cba7cc3424e2a83db6b186211d4e94f ]

- MLX5_VEC_TX_CKSUM_OFFLOAD_CAP became unused when Tx metadata moved
  to a dynamic field.
- MLX5_ALARM_TIMEOUT_US became unused when reworking link status wait.
- MLX5_FLOW_SFT_HLIST_ARRAY_SIZE was never used in hash list handling.
- MLX5_FLOW_MIN_ID_POOL_SIZE and MLX5_ID_GENERATION_ARRAY_FACTOR became
  unused when the flow ID generator was replaced by ipool.
- MLX5_RSSQ_DEFAULT_NUM was used in the old per-thread flow workspace.
- MLX5_FLOW_TABLE_HWS_POLICY became unused because meter is not supported
  in HWS.
- IPPROTO_MPLS became unused because MPLS over IP is not supported.
- MLX5_L4_RSS_TYPES has never been used.
- ETH_TYPE_IPV4/V6_VXLAN were never used in HWS.
- PCI_DRV_FLAGS became unused when migrating to bus-agnostic probing.

Fixes: 9bf26e1318e3 ("ethdev: move egress metadata to dynamic field")
Fixes: cfee94752b8f ("net/mlx5: fix link status to use wait to complete")
Fixes: f3020a331dca ("net/mlx5: optimize hash list table allocate on demand")
Fixes: 4ae8825c5085 ("net/mlx5: use indexed pool as id generator")
Fixes: dc7c5e0aa905 ("net/mlx5: fix flow workspace destruction")
Fixes: 645f240d1cd5 ("net/mlx5: remove unsupported flow meter action in HWS")
Fixes: 14ad99d78a46 ("net/mlx5: remove unsupported flow item MPLS over IP")
Fixes: ae67e3c43dd5 ("net/mlx5: support RSS expansion in non-template HWS setup")
Fixes: c55c2bf35333 ("net/mlx5/hws: add definer layer")
Fixes: a7f34989e9ad ("net/mlx5: migrate to bus-agnostic common interface")
