Right, pci-to-pcie bridge case isn't covered.
Although SERR bit can be set, the error can't be propagated up further
because qemu doesn't emulate PERR#/SERR#.
There is no use case of pci-to-pcie bridge in qemu, I think.
If good error handling is wanted, express should be used.
So it isn't worthwhile to implement pci-to-pcie bridge.
