 18           Support for Transformation(XFRM) user configuration interface
 19           like IPsec used by native Linux tools.

 25         depends on XFRM
 26         ---help---
 27           Support sub policy for developers. By using sub policy with main
 28           one, two policies can be applied to the same packet at once.
 29           Policy which lives shorter time in kernel should be a sub.

 35         depends on XFRM
 36         ---help---
 37           A feature to update locator(s) of a given IPsec security
 38           association dynamically.  This feature is required, for
 39           instance, in a Mobile IPv6 environment with IPsec configuration
 40           where mobile nodes change their attachment point to the Internet.
 41 
 42           If unsure, say N.

 48           This statistics is not a SNMP/MIB specification but shows
 49           statistics about transformation error (or almost error) factor
 50           at packet processing for developer.
 51 
 52           If unsure, say N.

 62         select XFRM_ALGO
 63         ---help---
 64           PF_KEYv2 socket family, compatible to KAME ones.
 65           They are required if you are going to use IPsec tools ported
 66           from KAME.
 67 
 68           Say Y unless you know what you are doing.
 69 
 70 config NET_KEY_MIGRATE
 71         bool "PF_KEY MIGRATE"
 72         depends on NET_KEY
 73         select XFRM_MIGRATE
 74         ---help---
 75           Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
 76           The PF_KEY MIGRATE message is used to dynamically update
 77           locator(s) of a given IPsec security association.
 78           This feature is required, for instance, in a Mobile IPv6
 79           environment with IPsec configuration where mobile nodes
 80           change their attachment point to the Internet.  Detail
 81           information can be found in the internet-draft
 82           <draft-sugimoto-mip6-pfkey-migrate>.
