I don't know if it is possible, but what would be best is that if no
packets are being dropped, then they should all have the same forwarding
(FIFO) priority, but if the router begins dropping packets it should
prefer dropping data packets over token packets. This will allow Spread
to do some higher level packet recovery without doing the work of
reforming the ring unnecessarily.
