0014 B.A.T.M.A.N. (better approach to mobile ad-hoc networking) is
0015 a routing protocol for multi-hop ad-hoc mesh networks. The
0016 networks may be wired or wireless. See
0017 https://www.open-mesh.org/ for more information and user space
0018 tools.

0024 help
0025 This option enables the B.A.T.M.A.N. V protocol, the successor
0026 of the currently used B.A.T.M.A.N. IV protocol. The main
0027 changes include splitting of the OGM protocol into a neighbor
0028 discovery protocol (Echo Location Protocol, ELP) and a new OGM
0029 Protocol OGMv2 for flooding protocol information through the
0030 network, as well as a throughput based metric.
0031 B.A.T.M.A.N. V is currently considered experimental and not
0032 compatible to B.A.T.M.A.N. IV networks.

0039 help
0040 This option enables BLA (Bridge Loop Avoidance), a mechanism
0041 to avoid Ethernet frames looping when mesh nodes are connected
0042 to both the same LAN and the same mesh. If you will never use
0043 more than one mesh node in the same LAN, you can safely remove
0044 this feature and save some space.

0050 help
0051 This option enables DAT (Distributed ARP Table), a DHT based
0052 mechanism that increases ARP reliability on sparse wireless
0053 mesh networks. If you think that your network does not need
0054 this option you can safely remove it and save some space.

0057 bool "Network Coding"
0058 depends on BATMAN_ADV
0059 help
0060 This option enables network coding, a mechanism that aims to
0061 increase the overall network throughput by fusing multiple
0062 packets in one transmission.
0063 Note that interfaces controlled by batman-adv must be manually
0064 configured to have promiscuous mode enabled in order to make
0065 network coding work.
0066 If you think that your network does not need this feature you
0067 can safely disable it and save some space.

0081 help
0082 This is an option for use by developers; most people should
0083 say N here. This enables compilation of support for
0084 outputting debugging information to the tracing buffer. The output is
0085 controlled via the batadv netdev specific log_level setting.

0091 help
0092 This is an option for use by developers; most people should
0093 say N here. Select this option to gather traces like the debug
0094 messages using the generic tracing infrastructure of the kernel.
0095 BATMAN_ADV_DEBUG must also be selected to get trace events for
0096 batadv_dbg.
