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?
