Hi Stephen,
If I understand correctly, do you mean that the internal value and rte_flow API value may have some conflict?
All the MLX5 internal enum values start from INT_MIN. When treating it as a int value, it would not have the same value with rte_flow enums, unless all the 2^^32 are defined.
But yes, this has some risk since there is no limitation of the values in the rte_flow API.
