I found MSI-x masking harder to test than we imagined. My plan is to only
emulate IO queues in the IOthread and leave admin queue emulation in the
main loop since some admin commands require BQL. So I didn’t enable irqfd on
admin queues. Therefore we can onlyt test MSI-x masking on IO queues. This
makes qtest complicated since we need to handle IO queue creation.

But I’m not sure my understanding is correct. Is it true that the admin
queue does not need irqfd as long as it runs in the main loop thread?
