> +DPAA2 is a hardware-level networking architecture found in some NXP SoCs which contains hardware blocks including Management Complex (MC, a command interface to manipulate DPAA2 objects), Wire Rate I/O processor (WRIOP, packets distribution, queuing, drop decisions), Queues and Buffers Manager (QBMan, Rx/Tx queues control, Rx buffer pools) and others.
> +The Management Complex runs NXP-supplied firmware which provides DPAA2 objects as an abstraction layer over those blocks to simplify access to the underlying hardware.
