OctetOK Count Interface
The statistics counters include two 64-bit counters,
RxOctetsOK
and
TxOctetsOK
, which count the
payload bytes (octets) in frames with no FCS, undersized, oversized, or payload length errors. The
RxOctetsOK
register maintains a cumulative count of the payload bytes in the qualifying received frames,
and complies with section 5.2.1.14 of the IEEE Standard 802.3-2008. The
TxOctetsOK
register maintains a
