- * This table shows various IO status codes from firmware and their

- * IO completions.
- *
- * BFI_IOIM_STS_OK : IO completed with error free SCSI &
- * transport status.
- * - io-tag can be reused.
- *
- * BFA_IOIM_STS_SCSI_ERR : IO completed with scsi error.
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_HOST_ABORTED : IO was aborted successfully due to
- * host request.
- * - io-tag cannot be reused yet.
- *
- * BFI_IOIM_STS_ABORTED : IO was aborted successfully
- * internally by f/w.
- * - io-tag cannot be reused yet.
- *
- * BFI_IOIM_STS_TIMEDOUT : IO timedout and ABTS/RRQ is happening
- * in the firmware and
- * - io-tag cannot be reused yet.
- *
- * BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO
- * with sequence level error
- * logic and hence host needs to retry
- * this IO with a different IO tag
- * - io-tag cannot be used yet.
- *
- * BFI_IOIM_STS_NEXUS_ABORT : Second Level Error Recovery from host
- * is required because 2 consecutive ABTS
- * timedout and host needs logout and
- * re-login with the target
- * - io-tag cannot be used yet.
- *
- * BFI_IOIM_STS_UNDERRUN : IO completed with SCSI status good,
- * but the data tranferred is less than
- * the fcp data length in the command.
- * ex. SCSI INQUIRY where transferred
- * data length and residue count in FCP
- * response accounts for total fcp-dl
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_OVERRUN : IO completed with SCSI status good,
- * but the data transerred is more than
- * fcp data length in the command. ex.
- * TAPE IOs where blocks can of unequal
- * lengths.
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag
- * during abort process
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_PROTO_ERR : Firmware detected a protocol error.
- * ex target sent more data than
- * requested, or there was data frame
- * loss and other reasons
- * - io-tag cannot be used yet.
- *
- * BFI_IOIM_STS_DIF_ERR : Firwmare detected DIF error. ex: DIF
- * CRC err or Ref Tag err or App tag err.
- * - io-tag can be reused.
- *
- * BFA_IOIM_STS_TSK_MGT_ABORT : IO was aborted because of Task
- * Management command from the host
- * - io-tag can be reused.
- *
- * BFI_IOIM_STS_UTAG : Firmware does not know about this
- * io_tag.
- * - io-tag can be reused.
