+Writing filemarks without the immediate bit set in the SCSI command block acts
+as a synchronization point, i.e., all remaining data form the drive buffers is
+written to tape before the command returns. This makes sure that write errors
+are caught at that point, but this takes time. In some applications, several
+consecutive files must be written fast. The MTWEOFI operation can be used to
+write the filemarks without flushing the drive buffer. Writing filemark at
+close() is always flushing the drive buffers. However, if the previous
+operation is MTWEOFI, close() does not write a filemark. This can be used if
+the program wants to close/open the tape device between files and wants to
+skip waiting.

If rewind, offline, bsf, or seek is done and previous tape operation was
write, a filemark is written before moving tape.

+ * - io-tag cannot be reused yet.
+ *
+ * BFI_IOIM_STS_ABORTED : IO was aborted successfully

+ * - 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,

+ * 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,

+ * 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

- * BFI_IOIM_STS_ABORTED : IO was aborted successfully

- * - 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.
