Tx PAUSE Frame Packets: The total number of good packets trans-
mitted that are Pause Control Frames. Only Pause Control Frames
which originated within the MAC are counted. Those that originated via
the SPI-3 interface are not counted.
Tx VLAN Tagged Packets: The total number of good packets transmit-
ted that are VLAN tagged (Type/Len Field = 0x8100)
Tx Deferral: A count of successfully transmitted packets for which the
first transmission attempt was deferred because the medium was busy.
The count does not include packets involved in collisions.
Tx Excess Deferral: A count of packets not transmitted because they
were deferred for an excessive period of time (3036 byte times).
Tx Single Collision: A count of successfully transmitted packets for
which transmission is inhibited by exactly one collision.
Tx Multiple Collision: A count of successfully transmitted packets for
which transmission is inhibited by more than one collision.
Tx Late Collision: A count of packets transmitted which experience a
late collision. A “late collision” is a collision detected more than 512 bit-
times into the transmission of a packet.
Note: Packet transmission can be continued or aborted by configuring
the Excessive Defer bit in the MAC’s Half-Duplex control register (Reg-
ister 0x400C Bit 16).
Tx Excessive Collision: A count of packets not transmitted due to
excessive collisions.
Tx Fragment Packets: The total number of packets transmitted that
were less than 64 octets in length (excluding framing bits but including
FCS octets) and had a bad Frame Check Sequence (FCS).
Tx FCS Errored Packets: The total number of packets transmitted that
had a length (excluding framing bits, but including FCS octets) of
between 64 and 1518 octets (1522 for VLAN tagged packets), inclu-
sive, but had a bad Frame Check Sequence (FCS).
Tx Jabber Packets: The total number of packets transmitted that were
longer than 1518 (1522 for VLAN tagged packets) octets (excluding
framing bits, but including FCS octets), and had a bad Frame Check
Sequence (FCS). This count will include packets truncated by the MAC
because they were longer than MAX octets.
MAX octets value is the “Maximum Frame Length” value programmed
in the MAC.
