Todo:
## Todo:
* Support multiple PCI devices, including specifying the PCI device by PCI
bus/domain/function.
* Define SPDK virtio bdev request structure and report it as the context
size during module initialization. This will allow the module to build
its request and response in per-bdev_io memory.
* Asynchronous I/O - currently the driver polls inline for all completions.
Asynchronous I/O should be used for both enumeration (INQUIRY, READ CAPACITY,
etc.) as well as read/write I/O.
* Add unmap support.
* Add I/O channel support. Includes requesting correct number of queues
(based on core count). Fail device initialization if not enough queues

linked directly to the bdev module. This would allow that part of the
code to potentially get used and tested outside of the SPDK bdev framework.
* Check for allocation failures in bdev_virtio.c code.
* Change printfs to SPDK_TRACELOGs (or just remove altogether).
* Add SPDK_TRACELOGs.
* Add virtio-blk support. This will require some rework in the core
virtio code (in the rte_virtio subdirectory) to allow for multiple
device types.

* Add reset support.
* Finish cleaning up "eth" references. This includes filenames like
virtio_ethdev.c and "eth" in various API calls.
* Improve the virtio_xmit_pkts and virtio_recv_pkts interfaces. Should not
reference the virtio_hw tx_queues directly. Should have a more opaque API.
* Understand and handle queue full conditions.
* Clear interrupt flag for completions - since we are polling, we do not
need the virtio-scsi backend to signal completion.
