[B.A.T.M.A.N.] [PATCH] batman-adv: move batadv_slide_own_bcast_window to bat_iv_ogm.c

Antonio Quartulli
2013-04-02T09:41:08Z

From: Antonio Quartulli <antonio@open-mesh.com>

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.
