I think what you are suggesting is a different action, by definition (at least in kernel)
The sample is a duplication of a packet, it comes to solve the lack of visibility when doing full offload.
What you are suggesting is to add 2 flows, like discussed in a different thread will have major impact on performance
(duplicate the matching, waste two flows since number of HW have limited rules capabilities )
Also it seems a bug that application can't relay to where the packet will get to. It will break applications that are
counting on traffic to get to a specific queue.

Best,
Ori
