What does the hardware look like and what is the problem you're trying
to solve here? Sending stream events into the core is a definite
layering violation and is likely to fail with some use case transitions
but without knowing what the patch is trying to achieve it's hard to
offer much advice.

Why is this an enumerated control and not a switch?
