TX 1024 to Max Bytes
Count of packets that have more than 1024 bytes.
Note:
Port x MAC Transmit 1024 to Max Byte Count Register (MAC_TX_1024_TO_MAX_CNT_x)
This register provides a counter of transmitted packets between the size of 1024 to the maximum
allowable number bytes. 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 5979 hours.
