P.S. 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.
