148 * BFI_IOIM_STS_HOST_ABORTED : IO was aborted successfully due to
149 * host request.
150 * - io-tag cannot be reused yet.
151 *
152 * BFI_IOIM_STS_ABORTED : IO was aborted successfully
153 * internally by f/w.
154 * - io-tag cannot be reused yet.
155 *
156 * BFI_IOIM_STS_TIMEDOUT : IO timedout and ABTS/RRQ is happening
157 * in the firmware and
158 * - io-tag cannot be reused yet.
159 *
160 * BFI_IOIM_STS_SQER_NEEDED : Firmware could not recover the IO
161 * with sequence level error
162 * logic and hence host needs to retry
163 * this IO with a different IO tag
164 * - io-tag cannot be used yet.
165 *
166 * BFI_IOIM_STS_NEXUS_ABORT : Second Level Error Recovery from host
167 * is required because 2 consecutive ABTS
168 * timedout and host needs logout and
169 * re-login with the target
170 * - io-tag cannot be used yet.
171 *
172 * BFI_IOIM_STS_UNDERRUN : IO completed with SCSI status good,
173 * but the data tranferred is less than
174 * the fcp data length in the command.
175 * ex. SCSI INQUIRY where transferred
176 * data length and residue count in FCP
177 * response accounts for total fcp-dl
178 * - io-tag can be reused.
179 *
180 * BFI_IOIM_STS_OVERRUN : IO completed with SCSI status good,
181 * but the data transerred is more than
182 * fcp data length in the command. ex.
183 * TAPE IOs where blocks can of unequal
184 * lengths.
185 * - io-tag can be reused.
186 *
187 * BFI_IOIM_STS_RES_FREE : Firmware has completed using io-tag
188 * during abort process
189 * - io-tag can be reused.
190 *
191 * BFI_IOIM_STS_PROTO_ERR : Firmware detected a protocol error.
192 * ex target sent more data than
193 * requested, or there was data frame
194 * loss and other reasons
195 * - io-tag cannot be used yet.
196 *
197 * BFI_IOIM_STS_DIF_ERR : Firwmare detected DIF error. ex: DIF
198 * CRC err or Ref Tag err or App tag err.
199 * - io-tag can be reused.
200 *
201 * BFA_IOIM_STS_TSK_MGT_ABORT : IO was aborted because of Task
202 * Management command from the host
203 * - io-tag can be reused.
