Patch series *) Adds support to add virtual functions to enable endpoint controller which supports SR-IOV capability *) Add support in Cadence endpoint driver to configure virtual functions *) Enable pci_endpoint_test driver to create pci_device for virtual functions Here both physical functions and virtual functions use the same pci_endpoint_test driver and existing pcitest utility can be used to test virtual functions also.
