Description

The current implementation of multicast forwarding will immediately settle the delivery on ingress to the router and forward the delivery as pre-settled.

This means the settlement state sent back to the producer provides no indication of actual delivery state. And the credit is replenished immediately rather than gate on the settlement coming from the consumer.

Improve this behavior by settling of the inbound delivery after all outbound deliveries have settled.
