I think having both "Flow control" and "Flow API" is confusing, it looks to me "Flow control" is name of the feature, "Flow API" is implementation detail and other implementation detail is "Flow director" >From the consumers point of view, to they need to know if the flow control implemented using "Flow API"? This information looks like more driver internal. Keeping only "Flow control" in feature list, and remove "Flow API" & "Flow director", and set "Flow control" as support both with implementations makes sense to me.
