RE: ISCSI: Urgent Flag requirement violates TCP.

I really wish you'd take hints ... a simple random scan
will have no problem picking SCSI CDBs and PDUs out of
an iSCSI stream without the Urgent mechanism, and
figuring out what the data is.  This particular obscurity
property of not knowing the alignment is so weak as to
be not worth the time spent discussing it (e.g., after
a pause in traffic, it's a good bet that the next TCP
segment has an iSCSI CDB or data PDU at its start),
and I again suggest leaving this rathole alone.
