SR-IOV - Single Root I/O Virtualization PF - Physical Function VF - Virtual Function If SR-IOV capability is present, use it to initialize Virtual Function PCI device instances. pci_sriov_init function will read SR-IOV registers to create VF devices under the PF PCI device and also bind driver if available. This function needs to be invoked from Physical function device driver which expects VF device support, creating minimal impact on existing framework.

Use driver model for PCI. Driver model is the new method for
