The commit ced72933a5 ("batman-adv: use CRC32C instead of CRC16 in TT
code") switched the translation table code from crc16 to crc32c. The
(optional) bridge loop avoidance code is the only user of this function.
batman-adv should only select CRC16 when it is actually using it.

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.

help
|
|
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.

help
|
|
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 debugfs log or tracing
