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
Frames bigger than the maximum allowed, with
both OK CRC and the integral number of octets.
Default maximum allowed is 1518 bytes
untagged and 1522 bytes tagged, but the value
can be changed by a register.
Frames bigger than the larger of
2*maxframesize and 50,000 bits are not counted
here, but they are counted in the VeryLongError
counter.
Frames bigger than the maximum allowed, with
either a bad CRC or a non-integral number of
octets. The default maximum allowed is 1518
bytes untagged and 1522 bytes tagged, but the
value can be changed by a register.
Frames bigger than the larger of
2*maxframesize and 50,000 bits are not counted
here, but they are counted in the VeryLongError
counter.
Number of Pause MAC control frames received.
This statistic register increments on any valid 64-
byte pause frame with a valid CRC and also
increments on a 64-byte pause frame with an
invalid CRC if bit 5 of the
Control ($ Port_Index + 0x19)
Number of MAC control frames received with an
op code different from 0001 (Pause).
