Hi Franz,
Thanks for providing the patch. We agree with the update and will check in your patch recently. Could you please let us know which Linux iSCSI target triggers this error? We may add more test items in future.
Best Regards, Ye Ting

Some simple value negotiation responses are optional, in particular DataPDUInOrder and DataSequenceInOrder. If we send "Yes", then the response from the target is optional, and the Linux target implementation does not return a response.
