snmp: add missing counters for RFC 4293
The IP MIB (RFC 4293) defines stats for InOctets, OutOctets, InMcastOctets and OutMcastOctets: http://tools.ietf.org/html/rfc4293 But it seems we don't track those in any way that easy to separate from other protocols. This patch adds those missing counters to the stats file. Tested successfully by me With help from Eric Dumazet. Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Signed-off-by: David S. Miller <davem@davemloft.net>
