If the traffic is processed by the PVA, it will not be analyzed by TMM (F5 kernel). PVA is limited, mainly IP and port, source and destination.

 

If you are doing just nPath, without IP encapsulation, it should work with PVA. If you need to do encapsulation, I doubt PVA can handle that, so it needs to be processed by TMM.
