      commit 5c43ad7f4d00160393e875088400cb2cf7adfe47

      ccw: be more precise about the semantic of revision 1

      Revision 1 of the CCW transport is currently defined as virtio 1.0. This
      could become confusing when we bump the version of the virtio
      specification to 1.1, in a sense that it could be interpreted like one
      can not use any features not part of the 1.0 specification.

      So let us try to avoid confusion regarding the semantic of virtio-ccw
      revision 1.
