The Spec says: The PSN of the retried RDMA READ request need not be the same as the PSN of the original RDMA READ request. Any retried request must correspond exactly to a subset of the original RDMA READ request in such a manner that all potential duplicate response packets must have identical payload data and PSNs regardless of whether it is a response to the original request or a retried request. It seems that a retransmitted READ must return identical data to the original. But consider this scenario a READ followed by WRITE followed by the original(retransmitted) READ. What is the expected response in this case? I tried this and it returns the latest value which is what I would expect. My question is why do we not return the original data?
