Unlike regular NICs, in the DPAA2 architecture there is no single hardware block

representing network interfaces; instead, several separate hardware resources

concur to provide the networking functionality:



- network interfaces

- queues, channels

- buffer pools
@@ -35,14 +33,13 @@ hardware resources, like queues, do not have a corresponding MC object and 
are treated as internal resources of other objects.

Each Linux net device is built on top of a Datapath Network Interface (DPNI)

object and uses Buffer Pools (DPBPs), I/O Portals (DPIOs) and Concentrators

(DPCONs).
