They are not network interfaces, so network core won't link them. They are for VM uses. I may need to explain this more clearly. PF's interface in sysfs is /sys/class/net/ethx, while VF has no interface. So 82576 driver makes directories to provide interface-like sysfs entries: /sys/class/net/ethx/vf[1-7] Make a link to this directory form VF's pci device is almost impossible, because PF doesn't know VF's bdf.
