batman-adv: Add kernel-doc to externally visible functions
According to the kernel-doc documentation, externally visible functions
should be documented. This refers to all all non-static function which can
(and will) be used by functions in other sources files.
Signed-off-by: Sven Eckelmann <sven(a)narfation.org>
