The files provided by batman-adv via debugfs are currently converted to
netlink. Tools which are not yet converted to use the netlink interface may
still rely on the old debugfs files. But systems which already upgraded
their tools can save some space by disabling this feature. The default
configuration of batman-adv on amd64 can reduce the size of the module by
around 11% when this feature is disabled.

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

https://www.open-mesh.org/ for more information and user space
|

tools.

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

|

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

This option enables DAT (Distributed ARP Table), a DHT based

mechanism that increases ARP reliability on sparse wireless

mesh networks. If you think that your network does not need

this option you can safely remove it and save some space.

help
|
|
This option enables network coding, a mechanism that aims to
|
|
increase the overall network throughput by fusing multiple
|
|
packets in one transmission.
|
|
Note that interfaces controlled by batman-adv must be manually
|
|
configured to have promiscuous mode enabled in order to make
|
|
network coding work.
|
|
If you think that your network does not need this feature you
|
|
can safely disable it and save some space.

This is an option for use by developers; most people should

say N here. This enables compilation of support for
|
|
outputting debugging information to the kernel log. The
|
|
output is controlled via the module parameter debug.
