Allow creating a zcrx instance without attaching it to a net device. All data will be copied through the fallback path. The user is also expected to use ZCRX_CTRL_FLUSH_RQ to handle overflows as it normally should even with a netdev, but it becomes even more relevant as there will likely be no one to automatically pick up buffers. Apart from that, it follows the zcrx uapi for the I/O path, and is useful for testing, experimentation, and potentially for the copy receive path in the future if improved.
