Device naming rules
- Onboard interfaces at firmware index numbers eno[1-N]
- Interfaces at PCI Express hotplug slot numbers ens[1-N]
- Adapters in the specified PCI slot, with slot index number on the adapter <templatestyles src="Mono/styles.css" />enp<PCI slot>s<card index no>
- If firmware information is invalid or rules are disabled, use traditional <templatestyles src="Mono/styles.css" />eth[0-N][1]
