Your options are:
1. Use the rdma plugin and create rdma interfaces.
2. Use the DPDK plugin. The DPDK build that is generated when you build VPP
will not include the mellanox PMDs by default. You need to explicitly
enable them when you build. There are build variables named DPDK_MLX5_PMD
and DPDK_MLX5_COMMON_PMD which have default values set to 'n'. Those need
to be set to 'y' to build the mlx5 PMD. You can set these by running
something like 'make DPDK_MLX5_PMD=y DPDK_MLX5_COMMON_PMD=y pkg-deb', or
you could edit build/external/packages/dpdk.mk and change the defaults
there.
