+ * Revision 1.1  2004/03/15 20:35:25  as
+ * added files from freeswan-2.04-x509-1.5.3
+ *
+ * Revision 1.7  2003/07/31 22:48:08  mcr
+ * 	derive NET25-ness from presence of NETLINK_XFRM macro.
+ *
+ * Revision 1.6  2003/06/24 20:22:32  mcr
+ * 	added new global: ipsecdevices[] so that we can keep track of
+ * 	the ipsecX devices. They will be referenced with dev_hold(),
+ * 	so 2.2 may need this as well.
+ *
+ * Revision 1.5  2003/04/03 17:38:09  rgb
+ * Centralised ipsec_kfree_skb and ipsec_dev_{get,put}.
+ *
+ * Revision 1.4  2002/04/24 07:36:46  mcr
+ * Moved from ./klips/net/ipsec/ipsec_kversion.h,v
+ *
+ * Revision 1.3  2002/04/12 03:21:17  mcr
+ * 	three parameter version of ip_select_ident appears first
+ * 	in 2.4.2 (RH7.1) not 2.4.4.
+ *
+ * Revision 1.2  2002/03/08 21:35:22  rgb
+ * Defined LINUX_KERNEL_HAS_SNPRINTF to shut up compiler warnings after
+ * 2.4.9.  (Andreas Piesk).
+ *
+ * Revision 1.1  2002/01/29 02:11:42  mcr
+ * 	removal of kversions.h - sources that needed it now use ipsec_param.h.
+ * 	updating of IPv6 structures to match latest in6.h version.
+ * 	removed dead code from freeswan.h that also duplicated kversions.h
+ * 	code.
