tcp analyzed out-of-order
This command allows you to define rule expressions to determine whether the received TCP packet was received before
all of the earlier sequenced packets have been received. This functionality is for whether the packet was analyzed or
discarded because the earlier sequenced packet(s) was (were) not received before a timeout expired.

Usage
This command is used to set the status flag to ‘analyzed’ or ‘not analyzed’ for all TCP packets received at the
ACSMgr/SessMgr prior to their earlier packets.
When a packet reaches ACSMgr/SessMgr prior to earlier packet(s), it and subsequent packets are buffered at
ACSMgr/SessMgr as TCP out-of-order packets and ACSMgr/SessMgr waits for missing packet(s) until the
time-out duration expires. If the packet(s) with the missing sequence number(s) arrives within the time-out
duration, all buffered packets with the correct sequence will be presented to upper layers (HTTP etc.) for
analysis; otherwise buffered TCP out-of-order packets will be sent to charging with analysis done flag at the
TCP/IP layer only.
