    [NETFILTER]: nf_nat: autoload IPv4 connection tracking
    
    Without this patch, the generic L3 tracker would kick in
    if nf_conntrack_ipv4 was not loaded before nf_nat, which
    would lead to translation problems with ICMP errors.
    
    NAT does not make sense without IPv4 connection tracking
    anyway, so just add a call to need_ipv4_conntrack().
