From 8ce68ceb55fb62d2c8e9a3e94c4ef6ff3e3064ce Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 13 Nov 2007 21:35:01 -0800 Subject: [IPSEC]: Only set neighbour on top xfrm dst The neighbour field is only used by dst_confirm which only ever happens on the top-most xfrm dst. So it's a waste to duplicate for every other xfrm dst. This patch moves its setting out of the loop so that only the top one gets set. Signed-off-by: Herbert Xu Signed-off-by: David S.
