Some fields in the hard-interface data structure are specific to the B.A.T.M.A.N. V protocol and have to be initialized only when such protocol is compiled in. Instead of having a #ifdef block in the middle of the hard-interface.c code it is better to have an algorithm private function that hides the precompiler logic in its own header file (like other functions).

Fixes: ffd2f27908e5 ("batman-adv: Only init ELP tweaking options when BATMAN_V is enabled") Signed-off-by: Antonio Quartulli a@unstable.cc ---

Changes from v1: - move bat_algo.h include line to the right location

Changes from v2: - rebased on top of newest master to fix compile error.
