Well, there is -hub, which is a kind of cheesy way of accomplishing this.
It wouldn't be hard to implement this for real. There's a bit of code
which figures out what port to send a packet to, based on whether it
has a MAC -> port mapping or whether the packet is multicast. Putting
something else in there to send everything to a certain port would be
straightforward.
You'd need an interface to it, and there is room for adding a command
line interface to the switch.
