The mesh/soft-interface can optimize the handling of DHCP packets. Instead of flooding them through the whole mesh, it can be forwarded as unicast to a specific gateway server. The originator which injects the packets in the mesh has to select (based on sel_class thresholds) a responsible gateway server. This is done by switching this originator to the gw_mode client. The servers announce their forwarding bandwidth (download/upload) when the gw_mode server was selected. The BATADV_CMD_SET_MESH/BATADV_CMD_GET_MESH commands allow to set/get the configuration of this feature using the attributes: * u8 BATADV_ATTR_GW_MODE (0 == off, 1 == client, 2 == server) * u32 BATADV_ATTR_GW_BANDWIDTH_DOWN (in 100 kbit/s steps) * u32 BATADV_ATTR_GW_BANDWIDTH_UP (in 100 kbit/s steps) * u32 BATADV_ATTR_GW_SEL_CLASS Signed-off-by: Sven Eckelmann <sven@narfation.org> Signed-off-by: Simon Wunderlich <sw@simonwunderlich.de>
