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 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.
