How so? The patch should make extended config space disappear when the
device is not on a PCIe bus. This is the correct behavior per the
PCIe spec. Are you trying to exploit this QEMU bug to see some PCIe
capabilities but not others? That's wrong, you'll need to move the
device to a PCIe slot to get extended capabilities.
