You're right something is wrong.
I should add a dereference.

Because I need good reviews from you and David :)
Will fix one and the other occurences.
I've prepared a v2 using a macro, but I think I will follow
your suggestion of having static inline functions.

You mean adding this after the lookup in the app?

It does. I can add a check.

Yes, udata64 was a trash bin used to store different kind of data,
even inside librte_security.

Yes, I think moving to a dedicated field is a first step.
Second step (not by me) will be to split in different fields.
