(Get the code!)
Due to new kernel patch here [1], the PF and VF representors are linked to their parent PCI device.
Old Structure:
The structure of VF's PCI Address/physfn/net contains only the PF of that VF
$ ls /sys/bus/
enp2s0f0
$ ls -l /sys/class/net
...
lrwxrwxrwx 1 root root 0 Aug 17 11:11 enp2s0f0_0 -> ../../devices/
lrwxrwxrwx 1 root root 0 Aug 17 11:11 enp2s0f0_1 -> ../../devices/
lrwxrwxrwx 1 root root 0 Aug 17 11:11 enp2s0f0_2 -> ../../devices/
lrwxrwxrwx 1 root root 0 Aug 17 11:11 enp2s0f0_3 -> ../../devices/
...
New Structure:
The structure of VF's PCI Address/physfn/net contains the PF of that VF and the VF representors
$ ls /sys/bus/
enp3s0f0 enp3s0f0_0 enp3s0f0_1 enp3s0f0_2 enp3s0f0_3
$ ls -l /sys/class/net
...
lrwxrwxrwx. 1 root root 0 Aug 17 08:43 enp3s0f0_0 -> ../../devices/
lrwxrwxrwx. 1 root root 0 Aug 17 08:43 enp3s0f0_1 -> ../../devices/
lrwxrwxrwx. 1 root root 0 Aug 17 08:43 enp3s0f0_2 -> ../../devices/
lrwxrwxrwx. 1 root root 0 Aug 17 08:43 enp3s0f0_3 -> ../../devices/
