Management firmware and driver are meant to be both backward and forward
compatibile with each other.

If a new mangement firmware would work with an older driver,
it's possible that driver would receive indications which are meaningless
to it. That's perfectly acceptible from the firmware part - so no need to
log such messages at default verbosity; That would only serve to confuse
users.
