NFP PMD has just had support for SRIOV VFs until now. This patchset adds
support for the PF, but just for being used as another DPDK port. No VF
management is added by now.
NFP is a programmable device and it supports virtual NICs (vNICs) through
firmware implementation. Different firmware applications implement vNICs
for PF devices and VF devices, being number of vNICs dependent on the
firmware and the NFP card available. PF vNIC (virtual) BARs are a subset
of PF PCI device BARs while VF vNIC BARs are same than VF PCI BARs.
Working with VF vNICs requires a PF driver uploading the firmware and
doing some NFP configuration. This needs can be only done with the kernel
NFP PF netdev driver by now.
Working with PF vNIC requires the PMD doing the NFP configuration and for
accessing the NFP a specific user space interface is created. NFP Service
Processor Userspace (NSPU) interface allows to create specific PCI BAR
windows for accessing different parts of the NFP device, including the
Network Service Processor (NSP) itself. The NSPU interface is implemented
as the base for working with the PF.
