23 tristate "B.A.T.M.A.N. Advanced Meshing Protocol"
27 B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
28 a routing protocol for multi-hop ad-hoc mesh networks. The
29 networks may be wired or wireless. See
30 https://www.open-mesh.org/ for more information and user space
33 config BATMAN_ADV_BATMAN_V
34 bool "B.A.T.M.A.N. V protocol"
35 depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y)
38 This option enables the B.A.T.M.A.N. V protocol, the successor
39 of the currently used B.A.T.M.A.N. IV protocol. The main
40 changes include splitting of the OGM protocol into a neighbor
41 discovery protocol (Echo Location Protocol, ELP) and a new OGM
42 Protocol OGMv2 for flooding protocol information through the
43 network, as well as a throughput based metric.
44 B.A.T.M.A.N. V is currently considered experimental and not
45 compatible to B.A.T.M.A.N. IV networks.
48 bool "Bridge Loop Avoidance"
49 depends on BATMAN_ADV && INET
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.
60 bool "Distributed ARP Table"
61 depends on BATMAN_ADV && INET
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.
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
79 If you think that your network does not need this feature you
80 can safely disable it and save some space.
82 config BATMAN_ADV_MCAST
83 bool "Multicast optimisation"
84 depends on BATMAN_ADV && INET && !(BRIDGE=m && BATMAN_ADV=y)
87 This option enables the multicast optimisation which aims to
88 reduce the air overhead while improving the reliability of
91 config BATMAN_ADV_DEBUGFS
92 bool "batman-adv debugfs entries"
96 Enable this to export routing related debug tables via debugfs.
97 The information for each soft-interface and used hard-interface can be
98 found under batman_adv/
102 config BATMAN_ADV_DEBUG
103 bool "B.A.T.M.A.N. debugging"
104 depends on BATMAN_ADV
106 This is an option for use by developers; most people should
107 say N here. This enables compilation of support for
108 outputting debugging information to the debugfs log or tracing
109 buffer. The output is controlled via the batadv netdev specific
112 config BATMAN_ADV_TRACING
113 bool "B.A.T.M.A.N. tracing support"
114 depends on BATMAN_ADV
115 depends on EVENT_TRACING
117 This is an option for use by developers; most people should
118 say N here. Select this option to gather traces like the debug
119 messages using the generic tracing infrastructure of the kernel.
120 BATMAN_ADV_DEBUG must also be selected to get trace events for
