> Currently old age action was implemented by flow counter and only one
> counter index was maintained in each flow. While there was old age
> action and share count action in one flow, and the same share count
> action in the another flow, the counter was updated if second flow
> was hit, so it may cause the first flow didn't aged out since the
> counter was updated by second flow.
> 
> This patch updates the validation function for count and old age action:
>   - Old age and shared count action combination is not supported.
>   - Old age and count(not shared) action could work in the same sub flow.
