Hi Ziye, The title would be better as "doc: add known issue with EAL argv" Also, below are some suggested changes to the docs in the patch: The last EAL argument is replaced by the program name in argv[] --------------------------------------------------------------- **Description**: The last EAL argument is replaced by the program name in ``argv[]`` after ``eal_parse_args()`` is called. This is the intended behavior but it causes the pointer to the last EAL argument to be lost. **Implication**: If the last EAL argument in ``argv[]`` is generated by a malloc function, changing it will cause memory issues when freeing the argument. **Resolution/Workaround**: An application should not consider the value in ``argv[]`` as unchanged. **Affected Environment/Platform**: All. **Driver/Module**: Environment Abstraction Layer (EAL).
