Hi Ben, DPDK is definitely supported in VPP but it has performance impacts and also carries a lot of dependencies (see for example the discussion on RISC-V: if DPDK was mandatory, we'd have to have both DPDK and VPP on RISC-V, but as VPP have native drivers too, we can get away without DPDK). VPP currently have native drivers for the following physical NICs: - avf: Intel with AVF support (Fortville and Columbiaville) - rdma: Mellanox mlx5 (ConnectX-4/5/6)
