17949        * For NCQ we need to issue READ LOG EXT command with log page 10h
17950        * to get the error and to allow other I/Os to continue.
17951        *
17952        * Here is the basic flow or sequence of error recovery, note that due
17953        * to the SATA HW assist that we have, this sequence is slighly different
17954        * from the one described in SATA 2.5:
17955        *
17956        * 1. Set SATA device flag to indicate error condition and returning busy
17957        *    for all new request.
17958        *   return tiSuccess;
17959 
17960        * 2. Because the HW/LL layer received Set Device Bit FIS, it can get the
17961        *    tag or I/O context for NCQ request, SATL would translate the ATA error
17962        *    to SCSI status and return the original NCQ I/O with the appopriate
17963        *    SCSI status.
17964        *
17965        * 3. Prepare READ LOG EXT page 10h command. Set flag to indicate that
17966        *    the failed I/O has been returned to the OS Layer. Send command.
17967        *
17968        * 4. When the device receives READ LOG EXT page 10h request all other
17969        *    pending I/O are implicitly aborted. No completion (aborted) status
17970        *    will be sent to the host for these aborted commands.
17971        *
17972        * 5. SATL receives the completion for READ LOG EXT command in
17973        *    satReadLogExtCB(). Steps 6,7,8,9 below are the step 1,2,3,4 in
17974        *    satReadLogExtCB().
17975        *
17976        * 6. Check flag that indicates whether the failed I/O has been returned
17977        *    to the OS Layer. If not, search the I/O context in device data
17978        *    looking for a matched tag. Then return the completion of the failed
17979        *    NCQ command with the appopriate/trasnlated SCSI status.
17980        *
17981        * 7. Issue abort to LL layer to all other pending I/Os for the same SATA
17982        *    drive.
17983        *
17984        * 8. Free resource allocated for the internally generated READ LOG EXT.
17985        *
17986        * 9. At the completion of abort, in the context of ossaSATACompleted(),
17987        *    return the I/O with error status to the OS-App Specific layer.
17988        *    When all I/O aborts are completed, clear SATA device flag to
17989        *    indicate ready to process new request.
