  In the rte_flow_field_data structure, the flex item handle is part
of union with other members like level/tag_index.

If the user wants to modify the flex item as source or destination,
there should not be any checking against zero.

Hi Rongwei,

I can't (also CI can't) apply this patch, on which tree it is based on?
