You might want to add why we want adapter interrupts:
- no test subchannel -> less qemu mutex contention
- no test subchannel -> we can...

[PATCH RFC] s390/virtio-ccw: Adapter interrupt support.
Handle the new CCW_CMD_SET_IND_ADAPTER command enabling adapter interrupts
on guest request. When active, host->guest notifications will be handled
via global_indicator -> queue indicators instead of queue indicators +
subchannel I/O interrupt. Indicators for virtqueues may be present at an
offset.
