[httperf] httperf IPv6 support

[Talgery, Hrishikesh]

  Hi,

  Does the latest version of htpperf support IPv6. We have added IPv6
  support to our product and need httperf for our testing. The version
  I downloaded  from 
     http://www.hpl.hp.com/research/linux/httperf/download.php

  does not support IPv6. Are there any plans to add IPv6 support. Even 
  a beta version would be helpful.

  Thanks,
  Hrishikesh Talgery
