Freescale's Layerscape Management Complex (MC) provide support various objects like DPRC, DPNI, DPBP and DPIO. Where: DPRC: Place holdes for other MC objectes like DPNI, DPBP, DPIO DPBP: Management of buffer pool DPIO: Used for used to QBMan portal DPNI: Represents standard network interface These objects are used for DPAA ethernet drivers.
