From edf391ff17232f097d72441c9ad467bcb3b5db18 Mon Sep 17 00:00:00 2001 From: Neil Horman Date: Mon, 27 Apr 2009 02:45:02 -0700 Subject: 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 Signed-off-by: David S.
