This attribute displays the number times that the out of sequence
packet threshold is exceeded. When the threshold is exceeded, this
condition is treated as if the loss frame timer has expired and all
frames queued at the sink Vc are delivered to the AP. We need to
keep this count to examine if the threshold is engineered properly.
This should be used in conjunction with the peak value of out-of-
sequenced queue and the number of times the loss frame timer has
expired. This count should be relatively small when compared with
loss frame timer expiry count.
