1. RO = Read Only, No clear on Read; R = Read, Clear on Read; W = Write only; R/W = Read/Write, No clear;
2. When sending in large frames, the counters can only handle certain limits. The behavior of the LongErrors
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).

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.

Description
The total number of packets received (including
bad packets) that were 256-511 octets in length.
Incremented for tagged packets with a length of
256-511 bytes, including tag field.
The total number of packets received (including
bad packets) that were 512-1023 octets in
length. Incremented for tagged packets with a
length of 512-1023 bytes, including tag field.
The total number of packets received (including
bad packets) that were 1024-1518 octets in
length. Incremented for tagged packet with a
length between 1024-1522, including the tag.
The total number of packets received (including
bad packets) that were greater than 1518 octets
in length. Incremented for tagged packet with a
length between 1523-max frame size, including
the tag.
Number of frames received with legal size, but
with wrong CRC field (also called Frame Check
Sequence (FCS) field).
Note:
Number of OK frames with VLAN tag.
(Type field = 0x8100)
Number of frames received with legal length,
containing a code violation (signaled with
RX_ERR on RGMII).
Frames with a legal frame size, but containing
less than eight additional bits. This occurs when
the frame is not byte aligned. The CRC of the
frame is wrong when the additional bits are
stripped. If the CRC is OK, then the frame is not
counted but treated as an OK frame. This
counter increments in 10 Mbps or 100 Mbps
RGMII mode only.
Note:
Legal size is 64 bytes through the value
programmed in the
Frame Size (Addr: Port_Index + 0x0F),

This counter increments in 10 or 100
Mbps RGMII mode only.
