The Mellanox CX-5 poll mode driver (PMD) is not built by default in some
configurations. 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:
