Can someone please forward this to the dev group? I sent a request for subscription but it is pending. I also went through the dev group threads but didn’t find a solution.

So say if RETA is programmed to receive on cores (0,1,2,3), then the new set would be (0,1,2). Existing flows going to (3) should be retained and forwarded. Only new flows should not be sent to (3).
