Description R/W Name Dword
Offset
The number of transmit frames with one the following errors:
• FIFO overflow error
• FIFO underflow error
• Errors defined by the user application
RO
ifOutErrors
0x23
The number of valid unicast frames received. RO ifInUcastPkts 0x24
The number of valid multicast frames received. The count
does not include pause frames. RO
ifInMulticastPkts
0x25
The number of valid broadcast frames received. RO ifInBroadcastPkts 0x26
This statistics counter is not in use.
The MAC function does not discard frames that are written
to the FIFO buffer by the user application.

ifOutDiscards
0x27
The number of valid unicast frames transmitted. RO
ifOutUcastPkts
0x28
The number of valid multicast frames transmitted, excluding
pause frames. RO ifOutMulticastPkts 0x29
The number of valid broadcast frames transmitted. RO
ifOutBroadcastPkts
0x2A
The number of frames that are dropped due to MAC internal
errors when FIFO buffer overflow persists. RO etherStatsDropEvents 0x2B
The total number of octets received. This count includes both
good and errored frames.
This register is the lower 32 bits of etherStatsOctets . The
upper 32 bits of this statistics counter reside at the dword offset
0x3E.
RO
etherStatsOctets
0x2C
The total number of good and errored frames received. RO
etherStatsPkts
0x2D
The number of frames received with length less than 64 bytes.
This count does not include errored frames. RO etherStatsUndersizePkts 0x2E
The number of frames received that are longer than the value
configured in the
frm_length
register. This count does not
include errored frames.
RO
etherStatsOversizePkts
0x2F
The number of 64-byte frames received. This count includes
good and errored frames. RO
etherStatsPkts64Octets
0x30
The number of received good and errored frames between the
length of 65 and 127 bytes. RO etherStatsPkts65to127Octets 0x31
The number of received good and errored frames between the
length of 128 and 255 bytes. RO
etherStatsPkts128to255Octets
0x32
The number of received good and errored frames between the
length of 256 and 511 bytes. RO etherStatsPkts256to511Octets 0x33
