1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No clear; R/W/C = Read/Write, Clear on Write

2. When sending in large frames, the counters can only handle certain limits. The behavior of the LongErrors and VeryLongErrors counters is as follows: VeryLongErrors counts frames that are 2*maxframesize, dependent upon where maxframesize is set. If maxframesize sets greater than half of the available count in RxOctetsBad (2^14-1), VeryLongErrors is never incremented, but LongErrors is incremented. This is due to a limitation in the counter size, which means that an accurate count will not occur in the RxOctetsBAD counter if the frame is larger than 2^14-1.

3. This register is relevant only when configured for copper operation.

4. This register is relevant only when configured for fiber operation (line side interface is SerDes).
