Previously we assumed that PCIe Root Ports and Downstream Ports had Links on their secondary side. That is true in most systems, but it is possible to connect a switch with either an Upstream or a Downstream Port leading downstream. Instead of relying on the component type to identify devices that have links leading downstream, use the "dev->has_secondary_link" field.
