Forgot to write something here in my previous reply, sorry...
The chain of bridges do not end with the connector in the in-kernel representation, IIUC. So, I think it is up to the caller to find the format desired by the connector. See patch [5/5] for an example.
Maybe the connector should be passed in as an argument?
