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 for virtio-net (header size and mac). - Dropped setting the VERSION_1 bit for virtio-blk: There's still some stuff missing. For virtio-blk, we need to validate the feature bits if version 1 is negotiated: some legacy features are not allowed in that case. I'm not quite sure how to handle this, though. We could use the new validate_features callback to verify that the driver negotiated a sensible feature set, but that would require us to offer a superset of legacy and version 1 bits, which feels wrong. Any ideas?
