Status SNACK requests for NOPIN

[santosh kulkarni <santosh.kulkarni@xxxxxxxxxxxxxx>]

Hi Nab,

I see that for  NOPOUT requests, in  scenarios where response for a 
NOPOUT,the NOPIN gets dropped
before it reaches the initiator and you request a retransmission through 
a Type 1 Status SNACK for that NOPIN.
What i see is that the target sends out a SCSI Response LUN (Op code 
0x21) instead of a NOPIN PDU. Is this an expected behaviour.

Also when i retry the NOPOUT with the same CmdSn the target is properly
ignoring it as duplicate since it has properly responded to the previous 
NOPOUT.
I don't see any logs in the dmesg.
PFA the pcap.

Please clarify.


Regards
Santosh
