    [IPV4] SNMP: Display new statistics at /proc/net/netstat
    
    This displays the statistics specified in the updated IP-MIB RFC
    (RFC4293) in /proc/net/netstat. The reason why these are not displayed
    in /proc/net/snmp is that some existing utilities are developed under
    the assumption which ipstat items in /proc/net/snmp is unchanged.
