Cornelia Huck updated VIRTIO-116:
---------------------------------

    Proposal: 
Failure scenarios for driver and device need to be documented:
- driver must check for failures of WRITE_STATUS and treat device as unusable
- device must post failure of WRITE_STATUS if the driver tries to set a wrong state
