           Summary: MP_PACKET_MINIMUM_PACKET_SIZE too small
           Product: RTEMS
           Version: HEAD
          Platform: All
        OS/Version: RTEMS
            Status: NEW
          Severity: normal
          Priority: P3
         Component: cpukit
        AssignedTo: joel.sherrill at oarcorp.com
        ReportedBy: sebastian.huber at embedded-brains.de


Currently we have sizeof(Message_queue_MP_Packet) >
MP_PACKET_MINIMUM_PACKET_SIZE (at least on PowerPC).  Therefore we should
increase MP_PACKET_MINIMUM_PACKET_SIZE.
