From dc00a525603650a1471c823a1e48c6505c2f9765 Mon Sep 17 00:00:00 2001 From: Masahide NAKAMURA Date: Wed, 23 Aug 2006 17:49:52 -0700 Subject: [PATCH] [XFRM] STATE: Allow non IPsec protocol. It will be added two more transformation protocols (routing header and destination options header) for Mobile IPv6. xfrm_id_proto_match() can be handle zero as all, IPSEC_PROTO_ANY as all IPsec and otherwise as exact one. Based on MIPL2 kernel patch. Signed-off-by: Masahide NAKAMURA Signed-off-by: YOSHIFUJI Hideaki Signed-off-by: David S.
