If iscsi-target returns 0 then user space keeps on retrying same command infinitely, targetcli or echo hangs till command completes with non zero return value. In some cases it is possible that add network portal command never completes with success even after retrying multiple times, for example - cxgbit_setup_np() always returns -EINVAL if portal IP does not belong to Chelsio adapter interface.
