 * dprc_assign() - Assigns objects or resource to a child container.
 * @mc_io:      Pointer to MC portal's I/O object
 * @cmd_flags:  Command flags; one or more of 'MC_CMD_FLAG_'
 * @token:      Token of DPRC object
 * @container_id: ID of the child container
 * @res_req:    Describes the type and amount of resources to
 *                      assign to the given container
 *
 * Assignment is usually done by a parent (this DPRC) to one of its child
 * containers.
 *
 * According to the DPRC allocation policy, the assigned resources may be taken
 * (allocated) from the container's ancestors, if not enough resources are
 * available in the container itself.
 *
 * The type of assignment depends on the dprc_res_req options, as follows:
 * - DPRC_RES_REQ_OPT_EXPLICIT: indicates that assigned resources should have
 *   the explicit base ID specified at the id_base_align field of res_req.
 * - DPRC_RES_REQ_OPT_ALIGNED: indicates that the assigned resources should be
 *   aligned to the value given at id_base_align field of res_req.
 * - DPRC_RES_REQ_OPT_PLUGGED: Relevant only for object assignment,
 *   and indicates that the object must be set to the plugged state.
 *
 * A container may use this function with its own ID in order to change a
 * object state to plugged or unplugged.
 *
 * If IRQ information has been set in the child DPRC, it will signal an
 * interrupt following every change in its object assignment.
 *
 * Return:      '0' on Success; Error code otherwise.
