  14           B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
  15           a routing protocol for multi-hop ad-hoc mesh networks. The
  16           networks may be wired or wireless. See
  17           https://www.open-mesh.org/ for more information and user space

  25           This option enables the B.A.T.M.A.N. V protocol, the successor
  26           of the currently used B.A.T.M.A.N. IV protocol. The main
  27           changes include splitting of the OGM protocol into a neighbor
  28           discovery protocol (Echo Location Protocol, ELP) and a new OGM
  29           Protocol OGMv2 for flooding protocol information through the
  30           network, as well as a throughput based metric.
  31           B.A.T.M.A.N. V is currently considered experimental and not
  32           compatible to B.A.T.M.A.N. IV networks.

  40           This option enables BLA (Bridge Loop Avoidance), a mechanism
  41           to avoid Ethernet frames looping when mesh nodes are connected
  42           to both the same LAN and the same mesh. If you will never use
  43           more than one mesh node in the same LAN, you can safely remove
  44           this feature and save some space.

  50         help
  51           This option enables DAT (Distributed ARP Table), a DHT based
  52           mechanism that increases ARP reliability on sparse wireless
  53           mesh networks. If you think that your network does not need
  54           this option you can safely remove it and save some space.

  58         depends on BATMAN_ADV
  59         help
  60           This option enables network coding, a mechanism that aims to
  61           increase the overall network throughput by fusing multiple
  62           packets in one transmission.
  63           Note that interfaces controlled by batman-adv must be manually
  64           configured to have promiscuous mode enabled in order to make
  65           network coding work.
  66           If you think that your network does not need this feature you
  67           can safely disable it and save some space.

  74           This option enables the multicast optimisation which aims to
  75           reduce the air overhead while improving the reliability of
  76           multicast messages.

  81         help
  82           This is an option for use by developers; most people should
  83           say N here. This enables compilation of support for
  84           outputting debugging information to the tracing buffer. The output is
  85           controlled via the batadv netdev specific log_level setting.

  92           This is an option for use by developers; most people should
  93           say N here. Select this option to gather traces like the debug
  94           messages using the generic tracing infrastructure of the kernel.
  95           BATMAN_ADV_DEBUG must also be selected to get trace events for
  96           batadv_dbg.
