Working with the PF requires access to the NFP for basic configuration. NSP is the NFP Service Processor helping with hardware and firmware configuration. NSPU is the NSP user space interface for working with the NSP. Configuration through NSPU allows to create PCI BAR windows for accessing different NFP hardware units, including the BAR window for the NSPU interface access itself. NFP expansion bar registers are used for creating those PCI BAR windows. NSPU uses a specific expansion bar which is reprogrammed for accessing/doing different things. Other expansion bars will be configured later for configuring the PF vNIC bars, a subset of PF PCI BARs. Signed-off-by: Alejandro Lucero <alejandro.lucero@netronome.com>
