As it’s info log level and not warning or notice, these message are useful in my opinion. You could downgrade them to debug, but I do not see why. If customers do not want to see these info messages, they should filter them out.

For completeness, is there an alternative to list the unsupported features from the firmware for example from sysfs?


Kind regards,

Paul

Don> Thanks for your Review.
At this time we would prefer to not provide messages about unsupported features. We may add them back at some point but we have taken them out of our out-of-box driver also so we hope to keep the driver code in sync.
