Chapter 6.3 of spec said

"
Transitional devices MUST offer, and if offered by the device
transitional drivers MUST accept the following:

"

virtio fixes for 2.4

Mostly virtio 1 spec compliance fixes.
We are unlikely to make it perfectly compliant in
the first release, but it seems worth it to try.
