 * 	*The Gateway callback should call batadv_gw_node_update()
 * 	*Remove it from bat_iv_ogm.c and use it in the gateway callback
 *	*Add this to sysfs.c -> batadv_gw_node_update()

 *   *Fix identation

 *   *Replace memcpy((char *)tvlv+sizeof(struct shortTvlv), value, length*sizeof(uint8_t));

* 	*batctl gwl
[4:35:36 PM] mareklindner: batadv_gw_node_update() ->  batctl gwl
[4:36:06 PM] mareklindner: disable aggregation
