What is network emulation?
I think that what you are suggesting is a different feature. There is high penalty for
rules duplication, like I stated in my previous reply.
As I can see there is no plan at least in Mellanox to support this kind of feature you
are suggesting, Since this API in any case is experimental. I suggest that when the need
comes or some other vendor will wish to implement such a feature we
can ether update the API or create a new one.
What do you think?
Best,
Ori
