[S390] qdio: Unrecognized inbound traffic if many FCP devices are online
Problem: Usually every FCP device has its own indicator field the adapter uses to signal outstanding work. Once a certain limit of devices is reached, a common indicator field is used. In certain scenarios qdio resets this common indicator field, but handles only part of the FCP-devices sharing the common indicator field. Thus inbound traffic on the non-processed shared FCP-devices is not recognized immediately. Solution: Make sure common indicator field is reset only, if all FCP-devices sharing the indicator are processed.
