The first few fields of 'cat /proc/bus/pci/devices' are understandable.

Field 1 - BusDevFunc
Field 2 - Vendor Id + Device Id
Field 3 - Interrupt Line
Field 4 - BAR 0
and the rest of the BAR registers (0 - 5) after that.

After the BAR registers are printed out, what are the other fields? Specifically, what PCI configuration space registers(offsets) are printed out?
