Hi David,

Thanks for the pointer. I did a quickly checking on the class number to see if
I could use it for differentiation the ports number. Whereas I found them 
both have the same class number as well. Below shows the "lspci" dump to 
all the PCI devices on Quark X1000 Galileo board (Ethernet controllers are
00:14.6 and 00:14.7). Very unfortunately we are unlikely to use the class 
number as well as pci_device_id for the differentiation.
Thanks.
