We have

/**
 *  This type defines the Multiprocessor Communications
 *  Interface (MPCI) Table.  This table defines the user-provided
 *  MPCI which is a required part of a multiprocessor system.
 *
 *  For non-blocking local operations that become remote operations,
 *  we need a timeout.  This is a per-driver timeout: default_timeout
 */
typedef struct {
  /** This fields contains the timeout for MPCI operations in ticks. */
  uint32_t                   default_timeout;
  /** This field contains the maximum size of a packet supported by this
   *  MPCI layer.  This size places a limit on the size of a message
   *  which can be transmitted over this interface.
   **/
  size_t                     maximum_packet_size;
  /** This field points to the MPCI initialization entry point. */
  MPCI_initialization_entry  initialization;
  /** This field points to the MPCI get packet entry point. */
  MPCI_get_packet_entry      get_packet;
  /** This field points to the MPCI return packet entry point. */
  MPCI_return_packet_entry   return_packet;
  /** This field points to the MPCI send packet entry point. */
  MPCI_send_entry            send_packet;
  /** This field points to the MPCI receive packet entry point. */
  MPCI_receive_entry         receive_packet;
} MPCI_Control;

Here we have the maximum_packet_size field.
