Ah, in that case it is because your libmlx5 is too old to support the new card you have: 18:00.0 Ethernet controller: Mellanox Technologies MT28800 Family [ConnectX-5] vs 81:00.0 Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5] You can upgrade it by building rdma-core from source.
