If I may chime in... regarding switching from MAC-based iface naming to
ID_NET_NAME_PATH-based naming. How exactly are these ID_NET_NAME_PATH
variables assigned?

For instance, I have a box with 2 pci intel cards:
1. DEVPATH=/devices/pci0000:00/0000:00:05.0/0000:02:00.0/net/elan0
   ID_NET_NAME_PATH=enp2s0f0
2. DEVPATH=/devices/pci0000:00/0000:00:06.0/0000:03:00.0/net/elan1
   ID_NET_NAME_PATH=enp3s0f0

Do I correctly understand that "enp?s0f0" is chosen based on a particular pci
slot the card is inserted in and will change if I choose to replug the cards?

Thanks,
