Right, this is the same machine Armen already sent, so I've CC'd him.

Looks like we're just adding the extra possible root ports from the PCI
IDs database:

2031	Sky Lake-E PCI Express Root Port B	
2032	Sky Lake-E PCI Express Root Port C	
2033	Sky Lake-E PCI Express Root Port D

Makes sense to me, thanks,
