15 B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
16 a routing protocol for multi-hop ad-hoc mesh networks. The
17 networks may be wired or wireless. See

25 help
26 This option enables the B.A.T.M.A.N. V protocol, the successor
27 of the currently used B.A.T.M.A.N. IV protocol. The main
28 changes include splitting of the OGM protocol into a neighbor
29 discovery protocol (Echo Location Protocol, ELP) and a new OGM
30 Protocol OGMv2 for flooding protocol information through the
31 network, as well as a throughput based metric.
32 B.A.T.M.A.N. V is currently considered experimental and not
33 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.

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.

57config BATMAN_ADV_NC
58 bool "Network Coding"
59 depends on BATMAN_ADV
60 help
61 This option enables network coding, a mechanism that aims to
62 increase the overall network throughput by fusing multiple
63 packets in one transmission.
64 Note that interfaces controlled by batman-adv must be manually
65 configured to have promiscuous mode enabled in order to make
66 network coding work.
67 If you think that your network does not need this feature you
68 can safely disable it and save some space.

94 This is an option for use by developers; most people should
95 say N here. This enables compilation of support for
96 outputting debugging information to the debugfs log or tracing
97 buffer. The output is controlled via the batadv netdev specific
98 log_level setting.

105 Say Y here if you want to enable batman-adv device configuration and
106 status interface through sysfs attributes. It is replaced by the
107 batadv generic netlink family but still used by various userspace
108 tools and scripts.

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
121 batadv_dbg.
