You wouldn't, because there could be *more than one* subtree with the
*same* "ett_" value.  "ett_" indices are for *types* of subtrees, not
for particular subtrees.

The answer is the same - there can be *more than one* protocol tree item
with a given header field ID, so there is no way to get *a* handle to a
protocol tree item if its header field index is known.

What are you trying to do?
