Ursula Braun 35b58b028d [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.
