Abstract
A Network Flow Processor (NFP) integrated circuit receives, via each of a first plurality of physical MAC ports, one or more PCP (Priority Code Point) flows. The NFP also maintains, for each of a second plurality of virtual channels, a linked list of buffers. There is one port enqueue engine for each physical MAC port. For each PCP flow received via the physical MAC port associated with a port enqueue engine, the port enqueue engine causes frame data of the flow to be loaded into one particular linked list of buffers. Each port enqueue engine has a lookup table circuit that is configurable to cause multiple PCP flows to be merged so that the frame data for the multiple flows is all assigned to the same one virtual channel. Due to the PCP flow merging, the second number can be smaller than the first number multiplied by eight.
