Greetings, Following patches are intended to support SR-IOV capability in the Linux kernel. With these patches, people can turn a PCI device with the capability into multiple ones from software perspective, which will benefit KVM and achieve other purposes such as QoS, security, and etc. Major changes between v4 -> v5: 1, remove interfaces for PF driver to create sysfs entries (Matthew
