Description

TCP stream objects may be swapped during protocol detection while opposing stream packet is being processed.
So the stream level functions try to insert this packet segment into the wrong stream after the detection phase.
It results either in StreamTcpReassembleHandleSegmentHandleData error or in packet data insertion to a wrong direction stream.
