11 tristate "B.A.T.M.A.N. Advanced Meshing Protocol"
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
20 config BATMAN_ADV_BATMAN_V
21 bool "B.A.T.M.A.N. V protocol"
22 depends on BATMAN_ADV && !(CFG80211=m && BATMAN_ADV=y)
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.
35 bool "Bridge Loop Avoidance"
36 depends on BATMAN_ADV && INET
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.
47 bool "Distributed ARP Table"
48 depends on BATMAN_ADV && INET
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.
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
66 If you think that your network does not need this feature you
67 can safely disable it and save some space.
69 config BATMAN_ADV_MCAST
70 bool "Multicast optimisation"
71 depends on BATMAN_ADV && INET && !(BRIDGE=m && BATMAN_ADV=y)
74 This option enables the multicast optimisation which aims to
75 reduce the air overhead while improving the reliability of
78 config BATMAN_ADV_DEBUG
79 bool "B.A.T.M.A.N. debugging"
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.
87 config BATMAN_ADV_TRACING
88 bool "B.A.T.M.A.N. tracing support"
90 depends on EVENT_TRACING
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
