Michael Tsirkin commented on VIRTIO-42:
---------------------------------------

So I think this SET_REVISION command isn't necessary anymore since we have the
transport independent FEATURES_OK command.
After this command, non-transitional devices can check VIRTIO_F_VERSION_1
to detect legacy drivers.

If you agree please close this issue.

> Allow drivers to select a revision they want to operate a device at, and allow devices to only support a subset of revisions.
> This allows non-transtional devices to reject operation by legacy drivers (see https://tools.oasis-open.org/issues/browse/VIRTIO-34).
