help
The Freescale Data Path Acceleration Architecture (DPAA) is a set of
hardware components on specific QorIQ multicore processors.
This architecture provides the infrastructure to support simplified
sharing of networking interfaces and accelerators by multiple CPUs.
The major h/w blocks composing DPAA are BMan and QMan.
The Buffer Manager (BMan) is a hardware buffer pool management block
that allows software and accelerators on the datapath to acquire and
release buffers in order to build frames.
The Queue Manager (QMan) is a hardware queue management block
that allows software and accelerators on the datapath to enqueue and
dequeue frames in order to communicate.

any use of the exported API. Not recommended for performance.
