A network interface that provides improved processing of received packets in a networked computer by classifying packets as they are received. Further, both the characteristics used by the network interface to classify packets and the processing performed on those packets once classified may be programmed. The network interface contains multiple receive queues and one type of processing that may be performed is assigning packets to queues based on classification. A network stack within an operating system of the networked computer can route packets classified by the network interface to application level destinations with reduced processing. Additionally, the priority with which packets of certain classifications are processed may be used to allocate processing power to certain types of packets. As a specific example, a computer subjected to a particular type of denial of service attack sometimes called a "SYN attack" may lower the priority of processing SYN packets to reduce the effect of such an attack.
