They do stay the same: Without the Board: DEVPATH=/devices/pci0000:00/0000:00:10.0/0000:04:00.0/net/eno2 DEVPATH=/devices/pci0000:00/0000:00:11.0/0000:05:00.0/net/mvc-sw1
With the Board: DEVPATH=/devices/pci0000:00/0000:00:10.0/0000:05:00.0/net/mvc-sw2 DEVPATH=/devices/pci0000:00/0000:00:11.0/0000:06:00.0/net/enp6s0 I'm assuming I can use this to match using glob ? If so, do I use the existing Path= or do I switch to DEVPATH ?
