Packet Forwarding Engine (PFE) Ethernet Ports Setting up on LS1012A Platform

[#1]

LS1012A integrates a hardware packet forwarding engine to provide high performance Ethernet interfaces. This document introduces PFE hardware and software decomposition and data flow, setting up two PFE Ethernet ports to implement Ethernet packets forwarding through PFE, how to modify PFE driver and dts file to set up single PFE Ethernet port on LS1012A custom boards.
