From 48bfee5fad0e46f4f18d46285efceba39e897482 Mon Sep 17 00:00:00 2001 From: Jing Min Zhao Date: Thu, 6 Apr 2006 14:13:42 -0700 Subject: [NETFILTER]: H.323 helper: move some function prototypes to ip_conntrack_h323.h Move prototypes of NAT callbacks to ip_conntrack_h323.h. Because the use of typedefs as arguments, some header files need to be moved as well. Signed-off-by: Jing Min Zhao Signed-off-by: Patrick McHardy Signed-off-by: David S.
