Can you point me to the logging in these other subsystems so I can
learn more about how they deal with this?

I agree that emitting log messages for normal and expected events will
lead to user confusion and we need to do something.

e8303bb7a75c ("PCI/LINK: Report degraded links via link bandwidth

time to figure this out before v5.1.
