PCI: Add support for PCIe-to-PCI bridge DMA alias quirks
Several PCIe-to-PCI bridges fail to provide a PCIe capability, causing us to handle them as conventional PCI devices when they really use the requester ID of the secondary bus. We need to differentiate these from PCIe-to-PCI bridges that actually use the conventional PCI ID when a PCIe capability is not present, such as those found on the root complex of may Intel chipsets. Add a dev_flag bit to identify devices to be handled as standard PCIe-to-PCI bridges. Signed-off-by: Alex Williamson <alex.williamson@redhat.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
