From 550ade8432a2a6fbfb48ba7018750b0e8c81e8d0 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Tue, 13 Nov 2007 21:33:01 -0800 Subject: [PATCH] [IPSEC]: Use dst->header_len when resizing on output Currently we use x->props.header_len when resizing on output. However, if we're resizing at all we might as well go the whole hog and do it for the whole dst. Signed-off-by: Herbert Xu Signed-off-by: David S.
