Abstract
A method for processing packets includes performing by a plurality of processors integrated in a single NIC chip, the plurality of processors including at least a hardware processor and a firmware processor, receiving information identifying at least one packet to be processed. The method may include determining whether the identified packet is a large send offload packet. If the identified packet is a large send offload packet, the method may include selecting between at least the hardware processor and the firmware processor to process the large send offload packet. If the identified packet is not a large send offload packet, the method may include bypassing the hardware process and the firmware process, and read DMA processing the identified packet from a host memory.
