Let me try to clarify what you mean. You would enforce such check in which function? Do you mean in any implementation of bbdev function taking enum rte_bbdev_op_type as argument?
In that case do you mean having in effect 2 values: 
- one for the number of supported implemented operation type = could be kept private within rte_bbdev.c implementation, purely to reject using a non-supported operation type
- and another higher value for padded maximum numbers of operations allowing for enumeration insertion.
That would sound fine to me, but please kindly confirm this is what you are implying. 
I will also check for Thomas feedback as well, thanks.
