This attribute records the number of times that the bus tap was
unable to receive a frame from the bus because it was destined for a
bus transmit queue; that is, the frame would have been immediately
retransmitted over a bus. Each occurrence results in the loss of the
frame. This type of event should never occur during normal
operation of the module and indicates the occurrence of a hardware
or software fault.
The attribute's value wraps around to zero when it exceeds the
maximum permitted value.
