In my case on the test machine, I have hierarchy of
pcib2 (PCIe port on host bridge with PCIe capability) -> pci2 ->
pcib3 (ITE PCIe/PCI bridge) -> pci3 -> em1
The device to check PCIe capability is pcib2 and not pcib3, as it is
currently done in the code. Also, in case of the bridge, we shall
step to pcib2 for the loop iteration, since pcib3 does not carry PCIe
capability info and would force wrong recalculation of rid.
Also change the returned requester to the PCIe bus which provides port
for the bridge. This only results in changing
hw.busdma.pciX.X.X.X.bounce tunable to force identity-mapped context
for the device.
