The number of packets transmitted. This
does not include packets transmitted with
errors (i.e., collision fragments and partial
packets due to transmit FIFO under runs).
The number of valid frames transmitted that
are addressed to a broadcast address. This
counter does not include errored broadcast
packets or valid multicast packets.
The number of valid frames transmitted that
are addressed to a multicast address. This
counter does not include errored multicast
packets or valid broadcast packets.
The number of collisions that occur during
transmission attempts. Collisions that occur
while the device is not transmitting (i.e.,
receive collisions) are not identifiable and
therefore not counted.
The number of valid frames transmitted that
are not addressed to a multicast or a
broadcast address. This counter does not
include errored unicast packets.
The number of packets successfully
transmitted after experiencing one collision.
The number of packets successfully
transmitted after experiencing more than one
collision.
The number of packets for which the first
transmission attempt on the network is
delayed because the medium is busy.
The number of late collisions that occur. A
late collision is defined as a collision that
occurs more than 512 bit times after the
transmission starts. The 512- bit interval is
measured from the start of preamble.
The number of excessive deferrals that occur.
An excessive deferral occurs when a
transmission is deferred for more than 3036
byte times in normal mode or 3044 byte times
in VLAN mode.
The number of transmit attempts made when
the LINK_STAT bit in the STAT0 register is 0.
The number of packets that are not
transmitted because the packet experienced
16 unsuccessful transmission attempts (the
first attempt plus 15 retries).
