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
18 tools.

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.

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

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

62 This option enables the multicast optimisation which aims to
63 reduce the air overhead while improving the reliability of
64 multicast messages.

66config BATMAN_ADV_DEBUG
67 bool "B.A.T.M.A.N. debugging"
68 depends on BATMAN_ADV
69 help
70 This is an option for use by developers; most people should
71 say N here. This enables compilation of support for
72 outputting debugging information to the tracing buffer. The output is
73 controlled via the batadv netdev specific log_level setting.

75config BATMAN_ADV_TRACING

77 depends on BATMAN_ADV
78 depends on EVENT_TRACING
79 help
80 This is an option for use by developers; most people should
81 say N here. Select this option to gather traces like the debug
82 messages using the generic tracing infrastructure of the kernel.
83 BATMAN_ADV_DEBUG must also be selected to get trace events for
84 batadv_dbg.
