Yoshinobu Inoue 4739b8076f IPv6 6to4 support. 
Now most big problem of IPv6 is getting IPv6 address
   assignment.
   6to4 solve the problem. 6to4 addr is defined like below,

          2002: 4byte v4 addr : 2byte SLA ID : 8byte interface ID

   The most important point of the address format is that an IPv4 addr
   is embeded in it. So any user who has IPv4 addr can get IPv6 address
   block with 2byte subnet space. Also, the IPv4 addr is used for
   semi-automatic IPv6 over IPv4 tunneling.

   With 6to4, getting IPv6 addr become dramatically easy.
   The attached patch enable 6to4 extension, and confirmed to work,
   between "Richard Seaman, Jr." <dick@tar.com> and me.
