It should be simple, removing the following code from 
br_input.c::br_handle_frame_finish() should probably be enough:
	dst = br_fdb_get(br, dest);
	if (dst != NULL && dst->is_local) {
		if (!passedup)
			br_pass_frame_up(br, skb);
		goto out;

	if (dst != NULL) {
		br_forward(dst->dst, skb);
		goto out;

It would probably be interesting to have a bridge userspace tool option so 
that the bridge acts like a hub, which is basically what you want.
