From 1b5c229987dc4d0c92a38fac0cde2aeec08cd775 Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Wed, 23 Aug 2006 18:11:50 -0700 Subject: [XFRM] STATE: Support non-fragment outbound transformation headers. For originated outbound IPv6 packets which will fragment, ip6_append_data() should know length of extension headers before sending them and the length is carried by dst_entry. IPv6 IPsec headers fragment then transformation was designed to place all headers after fragment header. OTOH Mobile IPv6 extension headers do not fragment then it is a good idea to make dst_entry have non-fragment length to tell it to ip6_append_data().
