From c439cb2e4b13cf1cb2abcd006b906315a3381323 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Fri, 11 Jan 2008 19:14:00 -0800 Subject: [IPV4]: Add ip_local_out Most callers of the LOCAL_OUT chain will set the IP packet length and header checksum before doing so. They also share the same output function dst_output. This patch creates a new function called ip_local_out which does all of that and converts the appropriate users over to it. Apart from removing duplicate code, it will also help in merging the IPsec output path once the same thing is done for IPv6. Signed-off-by: Herbert Xu Signed-off-by: David S.
