commit 68e981a3a2615fff7758f0f153117ece76bdb728 Author: Sven Eckelmann sven@narfation.org Date: Sat Feb 9 14:41:09 2019 +0100

batman-adv: Trigger genl notification on sysfs config change

The generic netlink code is expected to trigger notification messages when configuration might have been changed. But the configuration of batman-adv is most of the time still done using sysfs. So the sysfs interface should also trigger the corresponding netlink messages via the "config" multicast group.
