ABSTRACT:
A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, an improved mechanism for handling receipt of data packets in a system utilizing an offload network adapter. The offload network adapter may include logic that permits the offload network adapter to delay notification of data reception to the host system in different ways. The advantage of delaying the notice of data packet reception to the host system is the potential for aggregation of several data packets, which can arrive immediately after the first one, for example, in a single notification. Given a stream with continuous data packet arrival, a value may be set, either statically or dynamically, for notification delay and this value may be configurable for the host system per communication socket.
