The commit reverted in the first patch introduced a regression where only the first VF reports the correct config space size, subsequent VFs report 256 bytes of config space. Replace this in the second patch with an assumption that all VFs support extended config space by virtue of the SR-IOV spec requiring a PCIe capability and reachability of the PF extended config space already being proven by the existence of the VF.
