On the IXP4xx SoCs, the Network Processing Engine (NPE) is a small
|
|
processor that can load a firmware to perform offloading of networking
|
|
and crypto tasks. It also manages the MDIO bus to the ethernet PHYs
|
|
on the IXP4xx platform. All IXP4xx platforms have three NPEs at
|
|
consecutive memory locations. They are all included in the same
|
|
device node since they are not independent of each other.
