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

34config BATMAN_ADV_BATMAN_V
35 bool "B.A.T.M.A.N. V protocol"
36 depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y)
37 default y
38 help
39 This option enables the B.A.T.M.A.N. V protocol, the successor
40 of the currently used B.A.T.M.A.N. IV protocol. The main
41 changes include splitting of the OGM protocol into a neighbor
42 discovery protocol (Echo Location Protocol, ELP) and a new OGM
43 Protocol OGMv2 for flooding protocol information through the
44 network, as well as a throughput based metric.
45 B.A.T.M.A.N. V is currently considered experimental and not
46 compatible to B.A.T.M.A.N. IV networks.

48config BATMAN_ADV_BLA

50 depends on BATMAN_ADV && INET
51 default y
52 help
53 This option enables BLA (Bridge Loop Avoidance), a mechanism
54 to avoid Ethernet frames looping when mesh nodes are connected
55 to both the same LAN and the same mesh. If you will never use
56 more than one mesh node in the same LAN, you can safely remove
57 this feature and save some space.

59config BATMAN_ADV_DAT
60 bool "Distributed ARP Table"
61 depends on BATMAN_ADV && INET
62 default y
63 help
64 This option enables DAT (Distributed ARP Table), a DHT based
65 mechanism that increases ARP reliability on sparse wireless
66 mesh networks. If you think that your network does not need
67 this option you can safely remove it and save some space.

69config BATMAN_ADV_NC
70 bool "Network Coding"
71 depends on BATMAN_ADV
72 help
73 This option enables network coding, a mechanism that aims to
74 increase the overall network throughput by fusing multiple
75 packets in one transmission.
76 Note that interfaces controlled by batman-adv must be manually
77 configured to have promiscuous mode enabled in order to make
78 network coding work.
79 If you think that your network does not need this feature you
80 can safely disable it and save some space.

82config BATMAN_ADV_MCAST
83 bool "Multicast optimisation"

86 This option enables the multicast optimisation which aims to
87 reduce the air overhead while improving the reliability of
88 multicast messages.

95 Enable this to export routing related debug tables via debugfs.
96 The information for each soft-interface and used hard-interface can be
97 found under batman_adv/
98
99 If unsure, say N.

101config BATMAN_ADV_DEBUG
102 bool "B.A.T.M.A.N. debugging"
103 depends on BATMAN_ADV_DEBUGFS
104 help
105 This is an option for use by developers; most people should
106 say N here. This enables compilation of support for
107 outputting debugging information to the kernel log. The
108 output is controlled via the module parameter debug.
