| Count of packets that have between 64 and the maximum allowable number |
|
| |
| of bytes and have a bad FCS, but do not have an extra nibble. The max |
|
| |
| number of bytes is 1518 for untagged packets and 1522 for tagged packets. |
|
| |
| If Jumbo2K (bit 3) is set in the Port x MAC Receive Configuration Register |
|
| |
| (MAC_RX_CFG_x), the max number of bytes is 2048. |
|
| |
| Note: | This counter will stop at its maximum value of FFFF_FFFFh. |
