Test scenario is as follows. Some iSCSI initiator sends a Data-OUT PDU sequence such that the size of the data segment of any Data-OUT PDU is not block size multiples. Test if such complex Data-OUT PDU sequence is processed correctly. Desired Data Transfer Length is 5 * SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH / 2. Number of Data-OUT PDUs is 4. Length of the data segment of the first two PDUs are SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH / 2 - 4. Length of the data segment of the third PDU is SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH. Length of the data segment of the final PDU is SPDK_ISCSI_MAX_RECV_DATA_SEGMENT_LENGTH / 2 + 8. Three data buffers should be used and three subtasks should be created and submitted. The test scenario assume that a iscsi_conn_read_data() call could read the required length of the data and all read lengths are 4 bytes multiples. The latter is to verify data is copied to the correct offset by using data patterns.
