Below you describe that you setup the "wpa-roam" scheme of wpasupplicant
package. When using this mode, _wpa_supplicant_ does the "link detection", and
it notifies a listening wpa_cli daemon which in turn calls ifup/ifdown as
required. There is no use for ifplud in this mode, ifplugd will only get in the
way.

In /usr/share/doc/wpasupplicant/README.modes.gz ifplugd is not mentioned
in the roaming mode section, because it is not needed.
