Use "auto" if the network interface is a permanent one, and "allow-hotplug"
if it's a transient one (removable, whatever).

Interfaces configured as "auto" will be respected by systemd's
"network-online.target", meaning any service that you configure to
wait for network-online will wait for all "auto" interfaces to be
brought up.  It will not wait for "allow-hotplug" interfaces.
