> For now, only one ASO action is supported in a single flow.
> Flow with more than one ASO action should be rejected in the
> validation stage.
> 
> Flow with action non-shared AGE and COUNT together should be
> treated as non-ASO because AGE will fall back to use HW counter,
> not ASO hit object.
> 
> Group 0 will use HW counter for AGE action even if no COUNT action.

> This commit will reject patterns (no matter which group if transfer)
> like:
> 1. group 1 pattern... / end actions age / meter / end
> 2. group 1 pattern... / end actions conntrack / meter / end
> 3. group 1 pattern... / end actions age / conntrack... / end
> 
> If AGE comes together with COUNT in the above patterns, it's allowed.
