Is it expected to have the nics in this section when running them with

Yes it's normal for Mellanox, the mlx5_core driver implements the
kernel-side DPDK hook.
You'll see both the NIC in Linux, as well as in VPP:

But beware that your VPP packages need to explicitly be compiled with
DPDK_MLX_DEFAULT set, see build/external/packages/dpdk.mk.
