The network coprocessor (NetCP) is a hardware accelerator that processes Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsystem with a ethernet switch sub-module to send and receive packets. NetCP also includes a packet accelerator (PA) module to perform packet classification operations such as header matching, and packet modification operations such as checksum generation. NetCP can also optionally include a Security Accelerator(SA) capable of performing IPSec operations on ingress/egress packets. Keystone SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates per Ethernet port. NetCP driver has a plug-in module architecture where each of the NetCP sub-modules exist as a loadable kernel module which plug in to the netcp core. These sub-modules are represented as "netcp-devices" in the dts bindings. It is mandatory to have the ethernet switch sub-module for the ethernet interface to be operational. Any other sub-module like the PA is optional. Both GBE and XGBE network processors supported using common driver. It is also designed to handle future variants of NetCP.
