[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 <nakam@linux-ipv6.org> Signed-off-by: YOSHIFUJI Hideaki <yoshfuji@linux-ipv6.org> Signed-off-by: David S. Miller <davem@davemloft.net>
