Hi, If possible, the preferred way of using Mellanox NICs with VPP is with the native rdma driver instead of DPDK: https://docs.fd.io/vpp/21.06/df/d0e/rdma_doc.html Otherwise you can always try to rebuild DPDK with mlx5 support, see https://git.fd.io/vpp/tree/build/external/packages/dpdk.mk#n18 The instructions you refer to is out-of-date.
