Dear DPDK Users, I met a problem with DPDK 20.05 + Mellanox CX-5 NIC. Does anyone know how to fix it? Thanks a lot!

The issue is fixed after enable the MLX5_PMD flag. Sorry to disturb!

Thanks a lot! > > Problem: > Mellanox CX-5 card ok with DPDK 19.11.3 but failed with DPDK 20.05. > 20.05 Reports no ethernet device, ok with 19.11.3 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: https://doc.dpdk.org/guides/nics/mlx5.html Dave
