I just wanted to point out that, in the scenario above, correctly implemented drivers and user mode applications should also track link state changes (link speed mostly, but other factors could affect latency) and update corrections accordingly. Drivers should probably be given a chance to update the correction before user-mode is notified or you’d end up with driver defaults overriding user-mode settings.
