batman-adv: split out router from orig_node For the network wide multi interface optimization there are different routers for each outgoing interface (outgoing from the OGM perspective, incoming for payload traffic). To reflect this, change the router and associated data to a list of routers. While at it, rename batadv_orig_node_get_router() to batadv_orig_router_get() to follow the new naming scheme.

batman-adv: Receive fragmented packets and merge Fragments arriving at their destination are buffered for later merge. Merged packets are passed to the main receive function as had they never been fragmented. Fragments are forwarded without merging if the MTU of the outgoing interface is smaller than the size of the merged packet.

batman-adv: tvlv - basic infrastructure The goal is to provide the infrastructure for sending, receiving and parsing information 'containers' while preserving backward compatibility. TVLV (based on the commonly known Type Length Value technique) was chosen as the format for those containers. Even if a node does not know the tvlv type of a certain container it can simply skip the current container and proceed with the next. Past experience has shown features evolve over time, so a 'version' field was added right from the start to allow differentiating between feature variants - hence the name: T(ype) V(ersion) L(ength) V(alue). This patch introduces the basic TVLV infrastructure: * register / unregister tvlv containers to be sent with each OGM (on primary interfaces only) * register / unregister callback handlers to be called upon finding the corresponding tvlv type in a tvlv buffer * unicast tvlv send / receive API calls Signed-off-by: Marek Lindner <lindner_marek@yahoo.de> Signed-off-by: Spyros Gasteratos <morfeas3000@gmail.com> Signed-off-by: Antonio Quartulli <antonio@meshcoding.com>

batman-adv: reorder packet types Reordering the packet type numbers allows us to handle unicast packets in a general way - even if we don't know the specific packet type, we can still forward it. There was already code handling this for a couple of unicast packets, and this is the more generalized version to do that.

batman-adv: add bonding again With the new interface alternating, the first hop may send packets in a round robin fashion to it's neighbors because it has multiple valid routes built by the multi interface optimization. This patch enables the feature if bonding is selected. Note that unlike the bonding implemented before, this version is much simpler and may even enable multi path routing to a certain degree.
