605 *
606 * BFI_IOIM_STS_OK : IO completed with error free SCSI &
607 * transport status.
608 * io-tag can be reused.
609 *
610 * BFA_IOIM_STS_SCSI_ERR : IO completed with scsi error.
611 * - io-tag can be reused.
612 *
613 * BFI_IOIM_STS_HOST_ABORTED : IO was aborted successfully due to
614 * host request.
615 * - io-tag cannot be reused yet.
616 *
617 * BFI_IOIM_STS_ABORTED : IO was aborted successfully
618 * internally by f/w.
619 * - io-tag cannot be reused yet.
620 *
621 * BFI_IOIM_STS_TIMEDOUT : IO timedout and ABTS/RRQ is happening
622 * in the firmware and
623 * - io-tag cannot be reused yet.
624 *
625 * BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO
626 * with sequence level error
627 * logic and hence host needs to retry
628 * this IO with a different IO tag
629 * - io-tag cannot be used yet.
630 *
631 * BFI_IOIM_STS_NEXUS_ABORT : Second Level Error Recovery from host
632 * is required because 2 consecutive ABTS
633 * timedout and host needs logout and
634 * re-login with the target
635 * - io-tag cannot be used yet.
636 *
637 * BFI_IOIM_STS_UNDERRUN : IO completed with SCSI status good,
638 * but the data tranferred is less than
639 * the fcp data length in the command.
640 * ex. SCSI INQUIRY where transferred
641 * data length and residue count in FCP
642 * response accounts for total fcp-dl
643 * - io-tag can be reused.
644 *
645 * BFI_IOIM_STS_OVERRUN : IO completed with SCSI status good,
646 * but the data transerred is more than
647 * fcp data length in the command. ex.
648 * TAPE IOs where blocks can of unequal
649 * lengths.
650 * - io-tag can be reused.
651 *
652 * BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag
653 * during abort process
654 * - io-tag can be reused.
655 *
656 * BFI_IOIM_STS_PROTO_ERR : Firmware detected a protocol error.
657 * ex target sent more data than
658 * requested, or there was data frame
659 * loss and other reasons
660 * - io-tag cannot be used yet.
661 *
662 * BFI_IOIM_STS_DIF_ERR : Firwmare detected DIF error. ex: DIF
663 * CRC err or Ref Tag err or App tag err.
664 * - io-tag can be reused.
665 *
666 * BFA_IOIM_STS_TSK_MGT_ABORT : IO was aborted because of Task
667 * Management command from the host
668 * - io-tag can be reused.
669 *
670 * BFI_IOIM_STS_UTAG : Firmware does not know about this
671 * io_tag.
672 * - io-tag can be reused.
