CPP refers to the internal NFP Command Push Pull bus. This patch allows to create CPP commands from user space allowing to access any single part of the chip. This CPP interface is the base for having other functionalities like mutexes when accessing specific chip components, chip resources management, firmware upload or using the NSP, an embedded arm processor which can perform tasks on demand. NSP was the previous only way for doing things in the chip by the PMD, where a NSPU interface was used for commands like firmware upload or port link configuration. CPP interface supersedes NSPU, but it is still possible to use NSP through CPP. CPP interface adds a great flexibility for doing things like extended stats or firmware debugging.
