Internet Key Exchange daemon - kernel module source

 Openswan is an IPsec based VPN solution for the Linux kernel. It can use the
 native IPsec stack as well as the KLIPS kernel module. Both IKEv1 and IKEv2
 protocols are supported.
 .
 For support of the old-style KLIPS ipsecX network interfaces a custom
 kernel module is needed.
 .
 This package contains source code for the Openswan IPsec kernel module,
 which can be used with tools like module-assistant or kernel-package
 for manual building of local kernel images.
 .
 Kernel versions >= 2.6.23 no longer need to be patched to provide NAT
 Traversal support for KLIPS.
