net ipv6: Don't use sysctl tables with .child entries.
The sysctl core no longer natively understands sysctl tables with .child entries. Split the ipv6_table to remove the .child entries. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Acked-by: Pavel Emelyanov <xemul@parallels.com> Signed-off-by: David S. Miller <davem@davemloft.net>
