[PATCH 4/5] common/mlx5: remove useless constants

Thomas Monjalon
2025-11-02T15:57:14Z

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")
Cc: stable@dpdk.org
