From fdd908bd47b0b1fb0b2acf149fbf123fa0c90183 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 23 Feb 2006 16:19:26 -0800 Subject: [PATCH] [IPSEC]: Use TOS when doing tunnel lookups We should use the TOS because it's one of the routing keys. It also means that we update the correct routing cache entry when PMTU occurs. Signed-off-by: Herbert Xu Signed-off-by: David S.
