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 distributed_arp_table implementation is using the commands BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH to set/get the configuration of the u8 (boolean) BATADV_ATTR_DISTRIBUTED_ARP_TABLE attribute.
