The mesh interface can use multiple slave/hard-interface ports at the same time to transport the traffic to other nodes. The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the configuration of this feature using the BATADV_ATTR_BONDING_ENABLED attribute. Setting the u8 to zero will disable this feature and setting it to something else is enabling this feature.
