A given field could be both generated and not generated - some instances could come from a packet's contents and others could be calculated from other information.

I.e., "generated" is a property of an instance of a field, not of a field; that's why the code sample you showed has a separate call to proto_item_set_generated().

That may not be the case for *all* fields that have generated instances, but there might be some fields that have both generated and non-generated instances.
