Venkata, How will that work? If the RNIC offloads RDMA and TCP completely from the Operating System and does not share any state information then the application running on the host will never be in the position to utilize the socket interface to use the communication logic to send and receive data between the remote node and itself. Some information needs to be shared. How much of it and what exactly needs to be shared is the question.
