Comments on Virtio 1.0 cs03

[Kevin Lo <kevlo@kevlo.org>]

Hi,

After reading the specification, I have two minor comments.

First, sort device status field [1] in the section 2.1 to improve readability,
namely ACKNOWLEDGE (1), DRIVER (2), DRIVER_OK (4), FEATURES_OK (8),
DEVICE_NEEDS_RESET (64), FAILED (128).

Second, since vring* and VRING* have been replaced with virtq* and VIRTQ*
respectively, I suggesting renaming the header virtio_ring.h to virtio_queue.h
or fixing include guards to match the name of the header.

Thanks,
