Hello, can somebody please tell me whether lpbk_mode works for mellanox NICs? I found 65c9d24170c9 ("net/mlx5: enable loopback by configured mode") that seems to implement this feature for mlx5. But setting lpbk_mode in rte_eth_conf does not seem to work for me (ixgbe works with this).
Are there any other ways how to configure such HW loopback-mode mellanox NICs (both mlx5, mlx4)? Thanks Jan
