       *
       * For NCQ we need to issue READ LOG EXT command with log page 10h
       * to get the error and to allow other I/Os to continue.
       *
       * Here is the basic flow or sequence of error recovery, note that due
       * to the SATA HW assist that we have, this sequence is slighly different
       * from the one described in SATA 2.5:
       *
       * 1. Set SATA device flag to indicate error condition and returning busy
       *    for all new request.
       *   return tiSuccess;

       * 2. Because the HW/LL layer received Set Device Bit FIS, it can get the
       *    tag or I/O context for NCQ request, SATL would translate the ATA error
       *    to SCSI status and return the original NCQ I/O with the appopriate
       *    SCSI status.
       *
       * 3. Prepare READ LOG EXT page 10h command. Set flag to indicate that
       *    the failed I/O has been returned to the OS Layer. Send command.
       *
       * 4. When the device receives READ LOG EXT page 10h request all other
       *    pending I/O are implicitly aborted. No completion (aborted) status
       *    will be sent to the host for these aborted commands.
       *
       * 5. SATL receives the completion for READ LOG EXT command in
       *    satReadLogExtCB(). Steps 6,7,8,9 below are the step 1,2,3,4 in
       *    satReadLogExtCB().
       *
       * 6. Check flag that indicates whether the failed I/O has been returned
       *    to the OS Layer. If not, search the I/O context in device data
       *    looking for a matched tag. Then return the completion of the failed
       *    NCQ command with the appopriate/trasnlated SCSI status.
       *
       * 7. Issue abort to LL layer to all other pending I/Os for the same SATA
       *    drive.
       *
       * 8. Free resource allocated for the internally generated READ LOG EXT.
       *
       * 9. At the completion of abort, in the context of ossaSATACompleted(),
       *    return the I/O with error status to the OS-App Specific layer.
       *    When all I/O aborts are completed, clear SATA device flag to
       *    indicate ready to process new request.
