For individual instances implementing the MSS, you'll want a leaf.

The purpose of a typedef is having each of the places where MSS configuration or operational state is used have a consistent type/constraint and perhaps pointer into the TCP specs.

That way, as a theoretical example, you don't define MSS in one model as uint16 and another as uint32 with a range restriction - which might be how someone's implementation does it.
