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