  26           like IPsec used by native Linux tools.

  32         depends on XFRM
  33         ---help---
  34           Support sub policy for developers. By using sub policy with main
  35           one, two policies can be applied to the same packet at once.
  36           Policy which lives shorter time in kernel should be a sub.

  43         ---help---
  44           A feature to update locator(s) of a given IPsec security
  45           association dynamically.  This feature is required, for
  46           instance, in a Mobile IPv6 environment with IPsec configuration
  47           where mobile nodes change their attachment point to the Internet.
  48

  55           This statistics is not a SNMP/MIB specification but shows
  56           statistics about transformation error (or almost error) factor
  57           at packet processing for developer.

  71           PF_KEYv2 socket family, compatible to KAME ones.
  72           They are required if you are going to use IPsec tools ported
  73           from KAME.
  74
  75           Say Y unless you know what you are doing.

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