Update the ChannelLink interface to specifically return the LinkError struct. This error implements the ClearTextError interface, so will be picked up as a routing realted error by the router. With LinkErrors implemented, the switch now returns a LinkError for all failures on our incoming/outgoing link and ForwardingError when the failure occurs down the line.
