1. A method of transferring a packet to a host computer system, wherein the packet is received at a communication device from a network, comprising:

  • parsing a header portion of a first packet received at a network interface for the host computer system to determine if said first packet conforms to a TCP protocol;

    generating a flow key to identify a first communication flow that includes said first packet, wherein said flow key includes a TCP connection for the communication flow;

    associating an operation code with said first packet, wherein said operation code indicates a status of said first packet, including whether said packet is a candidate for transfer to the host computer system that avoids processing said header portion by the host computer system in accordance with said TCP protocol; and

    processing, by the network interface, said packet according to the TCP connection, including updating a control block representing the TCP connection on the network interface.
