ABSTRACT:
A network interface device includes a bus interface that communicates over a bus with a host processor and memory, and a network interface, including at least first and second physical ports, which are coupled to send and receive data packets carrying data over a packet network. A protocol processor includes a single transmit processing pipeline and a single receive processing pipeline, which are coupled between the bus interface and the network interface so as to convey the data between both of the first and second physical ports of the network interface and the memory via the bus interface while performing protocol offload processing on the data packets.
