RX Oversize
Count of packets that have more than the maximum allowable number of
bytes and a valid FCS. The max number of bytes is 1518 for untagged
packets and 1522 for tagged packets. If Jumbo2K (bit 3) is set in the

Note:
Port x MAC Receive Oversize Count Register (MAC_RX_OVRSZE_CNT_x)
This register provides a counter of received packets with a size greater than the maximum byte size.
The counter is cleared upon being read.
Note: For this counter, a packet with the maximum number of bytes that is not an integral number of
This counter will stop at its maximum value of FFFF_FFFFh.
Minimum rollover time at 100Mbps is approximately 8813 hours.
