netfilter buglog - Mar 2009 - [Bug 588] New: make ipv6 optional in iptables

http://bugzilla.netfilter.org/show_bug.cgi?id=588

           Summary: make ipv6 optional in iptables
           Product: iptables
           Version: CVS (please indicate timestamp)
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: ip6tables
        AssignedTo: laforge at netfilter.org
        ReportedBy: sf at cbg.dyndns.org


For use in embedded environments, it would be useful if IPv6 support could be
disabled via ./configure. This option was available in older versions, but then
removed.

------- Comment #1 from sf at cbg.dyndns.org  2009-03-30 18:36 -------
I get an error when trying to attach a file:

undef error - Undefined subroutine Fh::slice at
data/template/template/en/default/global/hidden-fields.html.tmpl line 58 

So my proposed patch comes here, sorry the for inconvenience:
