Is there a bug in STM32CubeMX code generation with STM32F4 library and LwIP ?

When enabling ICMP so that 'ping' is enable. It is(seems)  necessary to disable hardware CRC generation. In that case the choice 'software CRC generation' is (seems to be) stuck on 'disable' and 'ping' does not respond.

It is then necessary to add in lwipopts.h :

/* USER CODE BEGIN 1 */

/*** because of a bug in STM32CubeMX code generator ? ***/

&sharpundef CHECKSUM_GEN_ICMP

&sharpdefine CHECKSUM_GEN_ICMP         1

/* USER CODE END 1 */

#checksum_gen_icmp

    Hello,

    Please find attached my .ioc project description.

    The problem I am encountering concern LwIP

    configuration/Checksum/CHECKSUM_GEN_ICMP: the choice list is limited to

    'disable'.

    Many thanks.
