+ 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

+ depends on PACKAGE_kmod-batman-adv
+ 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.
