ABSTRACT:
A method of operating a system including a host and intelligent network interface circuitry extends a passive open operation to accomplish full offload of a stateful connection between a host and a peer. In response to observing a synchronization signal from the peer, an offload target creates a connection control block in the offload target in anticipation of a corresponding stateful connection being offloaded from the host. The observed synchronization signal is allowed to be provided to the host. In response to observing a synchronization acknowledgment signal from the host and destined for the peer, the offload target performs establishment processing for the stateful connection. Based on an acknowledgment of the synchronization acknowledgment signal from the peer, acknowledgement of the synchronization acknowledgement signal is processed and a corresponding acknowledgment signal is provided to the host. In response to receiving an offload event indication from the host, the stateful connection is operated between the host and the peer.
