  24           like IPsec used by native Linux tools.

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

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

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

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

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