commit 1ba02221962fa9fa1e9b32ed1e9ad01c3149c724 Author: Antonio Quartulli antonio@open-mesh.com Date: Wed Apr 17 17:44:43 2013 +0200

batman-adv: move batadv_slide_own_bcast_window to bat_iv_ogm.c

batadv_slide_own_bcast_window() is used only in bat_iv_ogm.c and it is currently touching only batman_iv specific attributes.

Move it into bat_iv_ogm.c and make it static.
