iSCSI version 0.6 - Query?

Hi,

Page 12, Last paragraph.

Regarding the command sequence number.

" The target MUST silently *ignore* any command outside this range or
duplicates with in the range that have not been flagged with the retry bit 
(the X bit in the opcode)"


Why ignore commands which are not in the expected range or duplicates
with in the range? This type of ignoring could  cause initator to
cause some unnecessary recovery activity which could/may end up to
be not good for the target which is hale and healthy. 

Such a  command could have been errorneously numbered or errorneously 
checked for this condition or errnoneously delivered with  sequence 
number change because of problems  transporting it over the internet fabric.

Hence, my opinion is appropriate error need to be returned for such command
instead of ignoring. 


Comments?
