+         Support for Transformation(XFRM) user configuration interface
+         like IPsec used by native Linux tools.
 
          If unsure, say Y.

+       bool "Transformation sub policy support (EXPERIMENTAL)"
+       depends on XFRM && EXPERIMENTAL
+       ---help---
+         Support sub policy for developers. By using sub policy with main
+         one, two policies can be applied to the same packet at once.
+         Policy which lives shorter time in kernel should be a sub.

+         A feature to update locator(s) of a given IPsec security
+         association dynamically.  This feature is required, for
+         instance, in a Mobile IPv6 environment with IPsec configuration
+         where mobile nodes change their attachment point to the Internet.
+
+         If unsure, say N.

+         If unsure, say N.

+         PF_KEYv2 socket family, compatible to KAME ones.
+         They are required if you are going to use IPsec tools ported
+         from KAME.
+
+         Say Y unless you know what you are doing.

+         Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
+         The PF_KEY MIGRATE message is used to dynamically update
+         locator(s) of a given IPsec security association.
+         This feature is required, for instance, in a Mobile IPv6
+         environment with IPsec configuration where mobile nodes
+         change their attachment point to the Internet.  Detail
+         information can be found in the internet-draft
