478 & 15 Mar 2015 & Cornelia Huck & {VIRTIO-129: legacy:
clean up virtqueue layout definitions
Generalize "Legacy Interfaces: A Note on Virtqueue Layout" to allow
for different alignment requirements. Have pci and ccw refer to that
section for legacy devices. Remove the double definition of virtqueue
alignment (which referred to legacy, but was not tagged as such) from
the ccw section.

479 & 15 Mar 2015 & Cornelia Huck & {VIRTIO-116:
ccw: allow WRITE_STATUS to fail
We want to be able to fail setting a status on the device
(e.g. FEATURES_OK if the device can't work with the features
negotiated).
The easiest way to do that is to allow the device to fail the
WRITE_STATUS command by posting a command reject.
