This attribute records the number of times that the bus tap was
unable to receive a frame from the bus because the delay between
two successive cells in that frame exceeded the maximum allowable
duration. Each occurrence results in the loss of the frame. This type
of event may occur during normal operation of the module, for
example when the module changes bus mode; it may also be caused
by a hardware fault.
The attribute's value wraps around to zero when it exceeds the
maximum permitted value.
