Models a generic wiring hub.

The model simply broadcasts messages (packets, frames, signals) received on one port on all other ports, mimicking the propagation of electrical signals. Messages are not interpreted by the model in any way, so this module is protocol agnostic.

Note that no special attention is made to appropriately model frame truncations that occur when the link breaks, or comes back up while a transmission is underway. If you need to precisely model what happens when the link state changes, you cannot use this module.
