iSCSI: Question on MaxCmdRN update rule

[Charles Monia <cmonia@NishanSystems.com>]

Hi Julo:

I don't understand the MaxCmdRN update policy as defined below:

"2.3.10 MaxCmdRN - maximum CmdRN acceptable from this initiator

MaxCmdRN is a reference number that the target iSCSI returns to the
initiator to indicate the maximum CmdRN the initiator can send. The
initiator must ignore values not between the current value of the
ExpCmdRN and MaxCmdRN; this may be required when updates arrive out
of order (they travel on different TCP connections)."

As I interpret the above, values not within the upper and lower limits given
above must be discarded.

I would think this parameter should be updated when a new value greater than
the current MaxCmdRN is received.
