* 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.
