Rather than using a vdev with args, DPDK can scan and initialize the
devices automatically using a bus-type driver. This bus does not need to
worry about registering device drivers, rather it can initialize the
devices directly on probe.
The device instances (queues) to use are detected from /dev with the
additional info about them got from /sys.
