Transmit CRC Error Statistics Counter (TX_STAT_CRC_ERR)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-21. Transmit CRC Error Statistics Counter Description
Name: TX_STAT_CRC_ERR
Bits Name
63:0 CRC_Error
Transmit Length Error Statistics Counter (TX_STAT_LNGTH_ERR)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-22. Transmit Length Error Length Statistics Counter Description
Name: TX_STAT_LNGTH_ERR
Bits Name
63:0 Length Error
Transmit Long Packet Statistics Counter (TX_STAT_LNG_PKT)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-23. Transmit Long Packet Statistics Counter Description
Name: TX_STAT_LNG_PKT
Bits Name
63:0 Long Packet
Transmit Multicast Packet Statistics Counter (TX_STAT_MLTCST)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-24. Transmit Multicast Packet Statistics Counter Description
Name: TX_STAT_MLTCST
Bits Name
63:0 Multicast Packet
Transmit Broadcast Packet Statistics Counter (TX_STAT_BRDCST)
A read of the low byte of this counter returns that byte and latches the upper bytes for later reading. A read of any
of the other bytes returns the previously latched value for that byte. The low address addresses the low byte.
Table 5-25. Transmit Broadcast Packet Statistics Counter Description
Name: TX_STAT_BRDCST
Bits Name
63:0 Broadcast Packet
IPUG39_02.9, December 2010
Type Default
Counts the total number of packets transmitted with crc error.
RO —
tx_statvec[22] is used to implement this counter.
Type Default
Counts the total number of packets transmitted with length of the
RO — packet and length in the Length/Type field mismatch.
tx_statvec[23] is used to implement this counter.
Type Default
Counts the total number of packets transmitted with length of the
RO — packet longer than the max_frm_size. tx_statvec[25] is used to
implement this counter.
Type Default
Counts the total number of multicast packets transmitted.
RO —
tx_statvec[20] is used to implement this counter.
Type Default
Counts the total number of broadcast packets transmitted.
RO —
tx_statvec[19] is used to implement this counter.
