"""Displays the name, IP address(es) and status of each available network interface.
Parameters:
* nic.exclude: Comma-separated list of interface prefixes to exclude (defaults to "lo,virbr,docker,vboxnet,veth")
* nic.states: Comma-separated list of states to show (prefix with "^" to invert - i.e. ^down -> show all devices that are not in state down)
* nic.format: Format string (defaults to "{intf} {state} {ip} {ssid}")
