      if [ "$(ip addr show ${IFACE} | grep 'inet ')" != ""  ]; then
         log_info_msg "Bringing down the ${IFACE} interface..."
         ip link set ${IFACE} down
         evaluate_retval
      fi

should be

      if [ "$(ip addr show ${IFACE} | grep 'inet ')" == ""  ]; then
         log_info_msg "Bringing down the ${IFACE} interface..."
         ip link set ${IFACE} down
         evaluate_retval
      fi
