    Perhaps it would also be better if the stats were stored as a ISO 8802.3
 MIB and made available via sysctl like what is done inside the if_ed driver.
 The struct for that looks like this:
 
 struct ifmib_iso_8802_3 {
         u_int32_t       dot3StatsAlignmentErrors;
         u_int32_t       dot3StatsFCSErrors;
         u_int32_t       dot3StatsSingleCollisionFrames;
         u_int32_t       dot3StatsMultipleCollisionFrames;
         u_int32_t       dot3StatsSQETestErrors;
         u_int32_t       dot3StatsDeferredTransmissions;
         u_int32_t       dot3StatsLateCollisions;
         u_int32_t       dot3StatsExcessiveCollisions;
         u_int32_t       dot3StatsInternalMacTransmitErrors;
         u_int32_t       dot3StatsCarrierSenseErrors;
         u_int32_t       dot3StatsFrameTooLongs;
         u_int32_t       dot3StatsInternalMacReceiveErrors;
         u_int32_t       dot3StatsEtherChipSet;
         /* Matt Thomas wants this one, not included in RFC 1650: */
         u_int32_t       dot3StatsMissedFrames;
 
         u_int32_t       dot3StatsCollFrequencies[16]; /* NB: index origin */
 
         u_int32_t       dot3Compliance;
 #define DOT3COMPLIANCE_STATS    1
 #define DOT3COMPLIANCE_COLLS    2
 };
 
    ...Garrett may be able to add more to this thought since he was the one
 who implemented the above.
