Re: iSCSI WRITE (10)

Response should be sent once, after all the write data ( I assume it is
unsolicited data) is received.

I -> T PDU 0x01 (scsi request), opcode 0x2a (WRITE 10)
I -> T PDU 0x05 (data out)
I -> T PDU 0x05 (data out)
...
T -> I PDU 0x21 (scsi response, for each data out)

Let me elaborate:

I -> T PDU 0x01 (scsi request), opcode 0x2a (WRITE 10)
T -> I PDU 0x21 (scsi response)
more data follows, so
I -> T PDU 0x05 (data out)
T -> I PDU 0x21 (scsi response, for each data out)
