Frame’s length/type field contained 8100h which is the VLAN protocol
identifier.
Carrier sense method backpressure was previously applied.
The frame transmitted was a control frame with a valid pause opcode.
The frame transmitted was a control frame.
Total bytes transmitted on the wire for the current packet, including all
bytes from collided attempts.
Reserved. This bit will always be ‘0’.
Byte count for frame was greater than MAMXFL.
Collision occurred beyond the collision window (MACLCON2).
Packet was aborted after the number of collisions exceeded the
retransmission maximum (MACLCON1).
Packet was deferred in excess of 24,287 bit times (2.4287ms).
Packet was deferred for at least one attempt but less than an excessive
defer.
Packet’s destination address was a broadcast address.
Packet’s destination address was a multicast address.
Transmission of the packet was completed.
Indicates that frame type/length field was larger than 1500 bytes (type
field).
Indicates that frame length field value in the packet does not match the
actual data byte length and is not a type field. MACON3.FRMLNEN
must be set to get this error.
The attached CRC in the packet did not match the internally generated
CRC.
Number of collisions the current packet incurred during transmission
attempts. It applies to successfully transmitted packets and as such, will
not show the possible maximum count of 16 collisions.
Total bytes in frame not counting collided bytes.
