[PATCH RFC v4 00/16] qemu: towards virtio-1 host support
Yet another version of the virtio-1 support patches.
This one has seen some (very) light testing with the virtio-1 guest
support patches currently on vhost-next.
Changes from v3:
- Add support for FEATURES_OK. We refuse to set features after the
driver has set this in the status field, and we allow to fail
setting the status if the features are inconsistent.
- Add missing virtio-1 changes
