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

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

  32           A feature to update locator(s) of a given IPsec security
  33           association dynamically.  This feature is required, for
  34           instance, in a Mobile IPv6 environment with IPsec configuration
  35           where mobile nodes change their attachment point to the Internet.
  36

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

  59           PF_KEYv2 socket family, compatible to KAME ones.
  60           They are required if you are going to use IPsec tools ported
  61           from KAME.
  62

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