41 * NSP is the NFP Service Processor. NSPU is NSP Userspace interface.
43 * NFP NSP helps with firmware/hardware configuration. NSP is another component
44 * in NFP programmable processor and accessing it from host requires to firstly
45 * configure a specific NFP PCI expansion BAR.
47 * Once access is ready, configuration can be done reading and writing
48 * from/to a specific PF PCI BAR window. This same interface will allow to
49 * create other PCI BAR windows for accessing other NFP components.
51 * This file includes low-level functions, using the NSPU interface, and high
52 * level functions, invoked by the PMD for using NSP services. This allows
53 * firmware upload, vNIC PCI BARs mapping and other low-level configurations
56 * NSP access is done during initialization and it is not involved at all with
