19 tristate "Transformation user configuration interface"
23 Support for Transformation(XFRM) user configuration interface
24 like IPsec used by native Linux tools.
28 config XFRM_SUB_POLICY
29 bool "Transformation sub policy support"
32 Support sub policy for developers. By using sub policy with main

34 Policy which lives shorter time in kernel should be a sub.
39 bool "Transformation migrate database"
42 A feature to update locator(s) of a given IPsec security

44 instance, in a Mobile IPv6 environment with IPsec configuration
45 where mobile nodes change their attachment point to the Internet.
49 config XFRM_STATISTICS
50 bool "Transformation statistics"
51 depends on INET && XFRM && PROC_FS

84 environment with IPsec configuration where mobile nodes
85 change their attachment point to the Internet. Detail
