Out Packets Number of packets send by the module, including broadcast packets

Alignment Errors Count of frames received that are not an integral number of octets in length

FCS Errors Count of frames that do not pass the FCS check

Carrier Sense Errors Number of times that the carrier sense condition was lost or never asserted when

attempting to transmit a frame

Excessive Collisions Count of frames when transmission fails caused by excessive collisions

Excessive Deferrals Count of frames when transmission is deferred for an excessive period of time

MAC Receive Errors Count of frames when transmission fails because of an internal MAC sublayer

receive error

MAC Transmit Errors Count of frames when transmission fails because of internal MAC sublayer

transmit error

Single Collisions Count of successfully transmitted frames when transmission is inhibited by one

collision

Multiple Collisions Ccount of successfully transmitted frames when transmission is inhibited by more

than one collision

Deferred Transmissions Count of frames when the first transmission attempt is delayed because the

medium is busy

Late Collisions Number of times that a collision is detected later than 512 bit-times into the

transmission of a packet
