commit a67a55a408f954fd44e5e9d6c3dd0d0ae141da6f Author: Sven Eckelmann sven@narfation.org Date: Sat Feb 9 14:42:14 2019 +0100
batctl: Support generic netlink for aggregation command
sysfs should be avoided for new settings of network interfaces. To still provide a common configuration infrastructure, all the existing settings subcommands also have to be reimplemented via generic netlink while still using sysfs as fallback.
The aggregation implementation is using the commands BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH to set/get the configuration of the u8 (boolean) BATADV_ATTR_AGGREGATED_OGMS_ENABLED attribute.
