Digging through the mlx5 driver source, it looks through the netlink kernel interface to get details about the hardware. Without access to the kernel data, DPDK can't init the mlx5 driver. You need to pass the interface into the container via the ip command https://stackoverflow.com/questions/60189587/how-to-pass-through-physical-nic-to-docker-container Thanks!
