Hold on... not sure what you mean by a "queue pair reset" but the IB spec does not say that a flush error should be generated when a QP is transitioned to the "reset" state. The flush error completions are required when a QP is transitioned to the "error" state, and in fact completion entries may be lost when a QP transitions to "reset". As far as I know every HCA supported by Linux does implement this correctly. Which class did you have in mind as not doing that? - R. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
