The least significant 8-bits of the total number of bytes transmitted on the wire, including all bytes
from collided attempts.
TXURUN: Transmit Under-Run
0: Transmit under-run did not occur.
1: Packet aborted due to data under-run condition.
TXJUMBO: Jumbo Packet Detected
0: Transmitted packet was not oversized.
1: Packet aborted due to its excessive size.
TXLTCL: Late Collision Detected
0: Late collision was not detected.
1: Packet aborted due to the detection of a collision after the 51.2 us collision window.
TXEXCL: Excessive Collisions Detected
0: Number of collisions on transmission was less than 16.
1: Packet aborted due to detection of 16 or more collisions.
TXEXDE: Excessive Delay Detected
0: Packet was transmitted without an excessive delay (greater than 2.42 ms). Please check other
flags for information.
