TX Deferred
Count of packets that were available for transmission but were deferred on
the first transmit attempt due to network traffic (either on receive or prior
transmission). This counter is not incremented on collisions. This counter is
incremented only in half-duplex operation.
Note:
Port x MAC Transmit Deferred Count Register (MAC_TX_DEFER_CNT_x)
This register provides a counter deferred packets. The counter is cleared upon being read.
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 481 hours.
