I notice most of these Device IDs are not in the lspci database at https://admin.pci-ids.ucw.cz/read/PC/0014. It's easy to add them; there's a link at the bottom of that page. Some, e.g., 0x7a09 (DEV_LS7A_PCIE_PORT0), are described as "PCI-to-PCI Bridge". I had the impression these were Root Ports. If so, the description could be more specific. Bjorn
