 How does it work ?
 ==================
 
-batctl uses the debugfs/batman_adv/bat0/socket device provided by the B.A.T.M.A.N.
-advanced kernel module to inject custom icmp packets into the data flow. That's why
-ping and traceroute work almost like their IP based counterparts. Tcpdump was
-designed because B.A.T.M.A.N. advanced encapsulates all traffic within batman
-packets, so that the normal tcpdump would not recognize the packets.

 The batman-adv kernel module comes with a variety of debug tables containing various information about the state of the mesh
-seen by each individual node. These tables are exported via debugfs and easily accessible via batctl. You will need debugfs
-support compiled into your kernel and preferably have mounted the debugfs to a well-known mountpoint. If debugfs is not
-mounted batctl will attempt to do this step for you.
