Antonio Quartulli	95d392784d	batman-adv: keep track of when unicast packets are sent ... To enable ELP to send probing packets over wireless links only if needed, batman-adv must keep track of the last time it sent a unicast packet towards every neighbour. For this purpose a 2 main changes are introduced: 1) a new member of the elp_neigh_node structure stores the last time a unicast packet was sent towards this neighbour; 2) a wrapper function for sending unicast packets is implemented. This function will simply update the member describe din point 1) and then forward the packet to the real sending routine. Point 2) implies that any code-path leading to a unicast sending now has to use the new wrapper.

Antonio Quartulli	0da0035942	batman-adv: OGMv2 - add basic infrastructure ... This is the initial implementation of the new OGM protocol (version 2). It has been designed to work on top of the newly added ELP. In the previous version the OGM protocol was used to both measure link qualities and flood the network with the metric information. In this version the protocol is in charge of the latter task only, leaving the former to ELP. This means being able to decouple the interval used by the neighbor discovery from the OGM broadcasting, which revealed to be costly in dense networks and needed to be relaxed so leading to a less responsive routing protocol.
