[PATCH RFC v2 1/4] virtio: add API to detect legacy devices
transports need to be able to detect legacy-only
devices (ATM balloon only) to use legacy path
to drive them.
Add a core API to do just that.
The implementation just blacklists balloon:
not too pretty, but let's not over-engineer.

[PATCH v3 0/6] virtio 1.0 enhancements
These are minor robustness enhancements on top of v8 of the patchset

As that one seems stable and actually seems to work well for people,
I'm not respinning it anymore.
