634 *
635 * BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO

638 * this IO with a different IO tag
639 * - io-tag cannot be used yet.

644 * re-login with the target
645 * - io-tag cannot be used yet.

649 * the fcp data length in the command.
650 * ex. SCSI INQUIRY where transferred
651 * data length and residue count in FCP

655 * BFI_IOIM_STS_OVERRUN : IO completed with SCSI status good,

658 * TAPE IOs where blocks can of unequal
659 * lengths.
660 * - io-tag can be reused.
661 *
662 * BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag
663 * during abort process
664 * - io-tag can be reused.
665 *
666 * BFI_IOIM_STS_PROTO_ERR : Firmware detected a protocol error.

670 * - io-tag cannot be used yet.
671 *

676 * BFA_IOIM_STS_TSK_MGT_ABORT : IO was aborted because of Task
