Table 15. Transmit Status Vector Description
Last frame transmitted had length/type field of 0x8100 (VLAN
protocol Identifier).
Back pressure was applied during transmission.
Last frame transmitted was a valid PAUSE control frame.
Last frame transmitted was a control frame.
Number of bytes transmitted on wire including all bytes from
collided attempts.
Last packet was aborted due to a data under-run condition.
Last packet was aborted due to the detection of a Jumbo
packet (oversized frame). Jumbo packets are not supported.
Last packet was aborted due to a collision occurring after the
51.2 µs collision window.
Last packet was aborted due to detection of 16 or more colli-
sions.
Aborted due to a delay longer than 2.42ms.
Last packet was transmitted, but had delay (less than 2.42
ms).
Last packet transmitted had a broadcast destination address.
Last packet transmitted had a multicast destination address.
Last packet was successfully transmitted.
Last packet’s length/type field had a value greater than 1500.
Last packet’s length/type field had a value less than or equal
to 1500 which did not match the actual frame length.
Last packet’s CRC field did not match the internally generated
CRC.
Number of collisions encountered during transmission of the
last packet.
Number of bytes in last frame not counting collided bytes.
