From 7b277b1a5fb147cb828e5d8b9780cee60f31a9bf Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 10 Oct 2007 15:44:06 -0700 Subject: [IPSEC]: Set skb->data to payload in x->mode->output This patch changes the calling convention so that on entry from x->mode->output and before entry into x->type->output skb->data will point to the payload instead of the IP header. This is essentially a redistribution of skb_push/skb_pull calls with the aim of minimising them on the common path of tunnel + ESP. It'll also let us use the same calling convention between IPv4 and IPv6 with the next patch. Signed-off-by: Herbert Xu Signed-off-by: David S.
