This patch show topology at forwarding start.

"show config fwd" also does this, but showing it directly can reduce the
possibility of misconfiguration.

[...]

-	fwd_config_setup();
+	fwd_config_display();
 	rxtx_config_display();

Having _display() calling _setup() is really strange.
Maybe it is worth to be fixed in this patch.
