This attribute displays the frame relay peak size of the
sequence packet queue. The subnet may deliver packets out-of-
sequenced. These packets are then queued in an out-of-sequenced
queue, waiting for a packet with the expected sequence number to
come. When that packet arrives, this attribute records the maximum
number of packets that were out-of-sequenced, but now have
become in-sequenced. The statistics is used to measure expected
queue size due to normal subnet packet disorder (not due to subnet
packet discard). Current implementation also uses this statistics to
set a maximum size for the out-of-sequenced queue.
