When using meson to build the framework the mlx5 dependencies are usually detected automatically and the PMD is built correctly. On the other hand, if you're building with GNU make then the MLX5 PMD needs to be specifically enabled by modifying a configuration file. Refer to the MLX5 PMD documentation for more details: https://doc.dpdk.org/guides/nics/mlx5.html Dave
