The following devices support both PCIe and legacy PCI, by
including special code to handle the QEMU_PCI_CAP_EXPRESS flag:

* vfio-pci (is_express=1, but legacy PCI handled by
   vfio_populate_device())
* vmxnet3 (is_express=0, but PCIe handled by vmxnet3_realize())
* pvscsi (is_express=0, but PCIe handled by pvscsi_realize())
* virtio-pci (is_express=0, but PCIe handled by
   virtio_pci_dc_realize(), and additional legacy PCI code at
   virtio_pci_realize())


Hi Eduardo,

We also have a "hybrid" USB controller (not sure which one :)).

Thanks,
Marcel
