When an iSCSI PDU header (Nop-In in the attached example) spans multiple TCP
segments, Wireshark doesn't correctly parse the PDU.
Packets 5-8 form a valid PDU IN (identical to the one in packet 3), but are not
correctly parsed as an iSCSI PDU, although the "Reassemble iSCSI messages
spanning multiple TCP segments" option is SET in the iSCSI preferences.
