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. Changes from v5 to v6: 1, update ABI document to include SR-IOV sysfs entries (Greg KH) 2, fix two coding
