From 776c729e8d91b2740583a2169678f2d3f383458b Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 14 Oct 2007 00:38:32 -0700 Subject: [IPV4]: Change ip_defrag to return an integer Now that ip_frag always returns the packet given to it on input, we can change it to return an integer indicating error instead. This patch does that and updates all its callers accordingly. Signed-off-by: Herbert Xu Signed-off-by: David S.
