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

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

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

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

  52           PF_KEYv2 socket family, compatible to KAME ones.
  53           They are required if you are going to use IPsec tools ported
  54           from KAME.

  63           Add a PF_KEY MIGRATE message to PF_KEYv2 socket family.
  64           The PF_KEY MIGRATE message is used to dynamically update
  65           locator(s) of a given IPsec security association.
  66           This feature is required, for instance, in a Mobile IPv6
  67           environment with IPsec configuration where mobile nodes
  68           change their attachment point to the Internet.  Detail
