  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

  20config BATMAN_ADV_BATMAN_V
  21        bool "B.A.T.M.A.N. V protocol"
  22        depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y)
  23        default y
  24        help
  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.

  34config BATMAN_ADV_BLA
  35        bool "Bridge Loop Avoidance"

  39        help
  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.

  46config BATMAN_ADV_DAT
  47        bool "Distributed ARP Table"
  48        depends on BATMAN_ADV && INET
  49        default y
  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.
  55
  56config BATMAN_ADV_NC
  57        bool "Network Coding"
  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.

  69config BATMAN_ADV_MCAST
  70        bool "Multicast optimisation"
  71        depends on BATMAN_ADV && INET && !(BRIDGE=m && BATMAN_ADV=y)
  72        default y
  73        help
  74          This option enables the multicast optimisation which aims to
  75          reduce the air overhead while improving the reliability of
  76          multicast messages.

  78config BATMAN_ADV_DEBUG
  79        bool "B.A.T.M.A.N. debugging"
  80        depends on BATMAN_ADV
  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.
  86
  87config BATMAN_ADV_TRACING
  88        bool "B.A.T.M.A.N. tracing support"

  90        depends on EVENT_TRACING
  91        help
  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.
