Hi, Based on your output, the ConnectX-4LX device is configured in LAG mode managed via the kernel bonding scripts. In this mode, both physical functions share a single port (mlx5_bond_0). You should only probe the first PCI BDF - 01:00.0, not the 2nd one.
By the way, the --dpdk installation flag should not be necessary, it is an old flag keps for Mellanox OFED builds lower than 5.x.
