      Description

      Within the Edd HAL Adapter for Cut-Through-Switch an invalid type is used when calling rX_DdpGetExtendedDeviceData to retrieve the Mac Address:

        GET_EXT_DEVICE_DATA_MAC_IN_T tIn;
        tResult = rX_DdpGetExtendedDeviceData(EXT_DEVICE_DATA_TYPE_MACADDR,
                                              sizeof(tIn), 
                                              &tIn, 
                                              sizeof(PND_MAC_ADDR_T), 
                                              &(tMacAddr[0]));

      The type of the destination should be GET_EXT_DEVICE_DATA_MAC_OUT_T and not PND_MAC_ADDR_T. The problem occurs as the type GET_EXT_DEVICE_DATA_MAC_OUT_T is a structure whereas PND_MAC_ADDR_T is an array of 6 UINT8. The structures size is eight bytes while the size of PND_MAC_ADDR_T is six bytes. The functions checks the argument size and fails due too small argument size.
