30.11  RMON Support
The Fast Ethernet controller can automatically gather network statistics required for
RMON without the need to receive all addresses using promiscuous mode. Setting
FPSMRx[MON] enables RMON support.
The RMON statistics and their corresponding counters in the parameter RAM are described
in Table 30-5.

etherStatsDropEvents
The total number of events in which packets were detected as 
dropped by the probe due to lack of resources. Note that this may 
not be the number of packets dropped; it is the number of times this 
condition is detected.
DISFC
 etherStatsOctets
The total number of octets of data (including those in bad packets) 
received on the network (excluding framing bits but including FCS 
octets).
OCTC
 etherStatsPkts
The total number of packets (including bad packets, broadcast 
packets, and multicast packets) received.

 etherStatsBroadcastPkts
The total number of good packets received that were directed to 
the broadcast address. Note that this does not include multicast 
packets.
BROC
 etherStatsMulticastPkts
The total number of good packets received that were directed to a 
multicast address. Note that this number does not include packets 
directed to the broadcast address.
MULC
etherStatsCRCAlignErrors
The total number of packets received that had a length (excluding 
framing bits but including FCS octets) of between 64 and 1518 
octets, inclusive, but had either an integral number of octets (FCS 
error) or a bad FCS with a non-integral number of octets (alignment 
error).

 etherStatsUndersizePkts
The total number of packets received that were less than 64 octets 
long (excluding framing bits but including FCS octets) and were 
otherwise well-formed.
USPC
 etherStatsOversizePkts
The total number of packets received that were longer than 1518 
octets (excluding framing bits but including FCS octets) and were 
otherwise well-formed.
