  New Revision: 35610

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=35610

  Log:
    Skip IPv6 addresses whose interface is set as IFDISABLED.
    
    FreeBSD 9.0 with default setting (ipv6_activate_all_interfaces
    is not YES) sets IFDISABLED to interfaces which don't have
    global IPv6 address.
    Link-local IPv6 addresses on those interfaces don't work.
