-## Purpose
-# This file is executed by ifupdown in pre-up, post-up, pre-down and
-# post-down phases of network interface configuration. It allows
-# ifup(8), and ifdown(8) to manage wpa_supplicant(8) and wpa_cli(8)
-# processes running in daemon mode.
-#
-# /etc/wpa_supplicant/functions.sh is sourced by this file.
-#
-# This file is provided by the wpasupplicant package.
