Per SRIOV SPEC sec 3.3.9, 3.3.10, offset/stride may change when NumVFs is written. While current kernel doesn't update offset/stride with the change of NumVFs. This property will also affect the iov bus range in enumeration. This patch set consists of two patches: 1. Update the offset/stride with NumVFs change 2. Calculate VF bus range on each possilbe NumVFs Code based on 3.19-rc1 and tested on x86 and powernv platform. Bus range doesn't chage on current hardware.
