* BFI_IOIM_STS_HOST_ABORTED : IO was aborted successfully due to

* - 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
