Port x MAC Receive 65 to 127 Byte Count Register (MAC_RX_65_TO_127_CNT_x)
This register provides a counter of received packets between the size of 65 to 127 bytes. The counter
is cleared upon being read.
Note: A bad packet is defined as a packet that has an FCS or Symbol error. For this counter, a packet
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 487 hours.
