counter is incremented when the result of a transmission is reported as
Transmit OK and the attempt value is 2.
ˆ
Frames Tx with more than one Collision . A count of frames that are
involved in more than one collision and are subsequently transmitted
successfully. This counter is incremented when the transmit status is
reported as
Transmit OK , and the value of the attempts variable is
greater than 2 and less or equal to the attempt limit.
ˆ
Frames Tx after Deferral . A count of frames whose transmission was
delayed on the first attempt because the medium was busy. The
frames involved in any collision are not counted.
