*-over-virtio

[Sasha Levin <sasha.levin@oracle.com>]

Hi all,

We seem to have a family of several devices that are rather simple on the virtio level. Some
identifying features include:

 * No real usage of the configuration space
 * No device features
 * No control vqs
 * Usually one, but possibly 2 vqs used for straightforward message passing outside the virtio
scope.

The use case is simple: use virtio as a simple transport for protocol specific messages, this
can pretty much go over any other transport exactly the same way.

Would it make sense to move their actual definition out of the spec and just reserve device
IDs for them there?


Thanks,
Sasha
