This include hardware (PCI), and virtualization (virtio, hyperv) where memory normally used by kernel can be mmapd for userspace driver. It is also possible to use DPDK virtual devices (tap, packet, xdp) which use existing kernel API's to access packets. These are slower but more general. Not sure what you expect here. Loopback device in kernel is special, and trying to make that go to DPDK would be hard.
