*!  \brief  itdssTaskCompleted
*
*  Purpose: This routine is called to complete an task management request
*           previously issued to the LL Layer. All task management completes with
*           this function except query task management.
*
*   \param  agRoot:         Pointer to driver Instance.
*   \param  agIORequest:    Pointer to the I/O Request data structure for
*                           this I/O.
*   \param  agIOStatus:     Status of I/O just completed.
*   \param  agIOInfoLen:    Length of the I/O information associated with this
*                           I/O request
*   \param   agParam        A Handle used to refer to the response frame or handle
*                           of abort request
*   \param  agOtherInfo        Residual count
*   \return:                None
*
*   \note - This is a initiator specific function called by the jump table.
