      Description

      For virtio-ccw devices using classic queue indicators, we cannot handle devices with more than 64 queues as the indicator value is a 64 bit integer and we would not be able to notify for the higher number virtqueues. The driver needs to use two-stage indicators if a device has more than 64 virtqueues.
