The batman-adv configuration interface was implemented solely using sysfs. This approach was condemned by non-batadv developers as "huge mistake". Instead a netlink/genl based implementation was suggested. Beside the mesh/soft-interface specific configuration, the VLANs on top of the mesh/soft-interface have configuration settings. The genl interface reflects this by allowing to get/set it using the vlan specific commands BATADV_CMD_GET_VLAN/BATADV_CMD_SET_VLAN. The set command BATADV_CMD_SET_MESH will also notify interested userspace listeners of the "config" mcast group using the BATADV_CMD_SET_VLAN command message type that settings might have been changed and what the current values are.
