-Move into mainline proper.
+ * Use hweight* for hamming weight calculation
+ * Save/cache packets direktly as skb instead of using a normal memory region
+   and copying it in a skb using send_raw_packet and similar functions
+ * Request a new review

+Description:
+                Each batman node only maintains information about its
+                own local neighborhood, therefore generating graphs
+                showing the topology of the entire mesh is not easily
+                feasible without having a central instance to collect
+                the local topologies from all nodes. This file allows
+                to activate the collecting (server) mode.
