There is - retrieving the value and adding it to the tree with
proto_tree_add_uint().
That way:
1) it's a registered field;
2) it's an integral field, not a string;
3) you don't have to worry about bit masks in the fields.
The fields, in this case, would *not* have bit masks, and would have a
size that's the size of the field rounded up to the lowest of (8, 16,
24, 32, 64).
