  * @return  0 on success
- * @return  -EAGAIN, if DTLS_HANDSHAKE_TIMEOUT is `0` and no data is available.
+ * @return  -EAGAIN, if @p timeout is `0` and handshake started.

How about this: remove the timeout here and use `session_create` _always_ to just initialize the handshake. It than _has_ to be finished with `sock_dtls_recv()` for which we re-specify the scope as such.
