[Click] IPsec ESP support

[Dimitris Syrivelis]

  Hello, 
 
    For the purposes of our research on network security, we have revived (to 
a certain extend) IPsec ESP support for the click router. 
  We have changed the IP routing modules to use a Security Association 
Database and we have added support for AES encryption, HMAC SHA1 
authentication and Replay prevention. 
 Please find attached a tarball with a patch against the click-1.5.0 release 
along with short documentation and a click configuration file that 
demonstrates our design choices. We have tested it on the linux module 
version of click.
 I would appreciate feedback and would be happy to discuss possible changes on 
our approach. Finally I would like to thank you all very much for making 
click publicly available.

  Best regards,

      Dimitris
