* BFI_IOIM_STS_ABORTED : IO was aborted successfully

* BFI_IOIM_STS_TIMEDOUT : IO timedout and ABTS/RRQ is happening

* - io-tag cannot be reused yet.
*
* BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO

* - io-tag cannot be used yet.
*
* BFI_IOIM_STS_NEXUS_ABORT : Second Level Error Recovery from host

* - io-tag cannot be used yet.
*
* BFI_IOIM_STS_UNDERRUN : IO completed with SCSI status good,

* - io-tag can be reused.

* BFI_IOIM_STS_OVERRUN : IO completed with SCSI status good,

* - io-tag can be reused.
*
* BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag

* - io-tag can be reused.

* BFI_IOIM_STS_DIF_ERR : Firwmare detected DIF error. ex: DIF
