Yes, I should include more pci info in patch comments:

root complex: 80:02.2
pci express modules: have pcie switch and are listed as b0:00.0,
b1:02.0 and b1:03.0.
                 end devices  are b2:00.0 and b3.00.0.
                 VFs are: b2:00.1,... b2:00.3, and b3:00.1,...,b3:00.3

Thanks

Yinghai Lu
