//
// An Ethernet hub model.
//
// The model simply broadcasts frames (and transmission updates
// representing aborted frames, etc.) received on one port on all
// other ports, mimicking the propagation of electrical signals.
//
// 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.
