For maximum flexibility, the flow control logic can be disabled in the core and alternatively implemented in the user logic connected to the core. Any type of error-free Control frame is then passed through the core without error.

In this way, the frame is passed to you for interpretation. It is your responsibility to drop this control frame and to act on it by ceasing transmission through the core, if applicable.
