message:
  Bug about VLAN's port numbering fixed. The procedure (now a method) to launch internal cables has changed in order to prevent the "port inversion" that can be observed: sometimes vde_switch may have an internal port numbering different from marionnet (and it is obviously a big problem for students when configuring VLANs). The protocol implemented in the new switch method (spawn_internal_cables) should ensure that vde_switch will not be solicited before having accepted the previously asked connection. However, in practice, vde_switch often continues to "invert" ports (as when super#spawn_internal_cables is called). Thus, a 0.5 seconds delay per port allocation is also performed (=> 4 seconds to start a 8-ports switch, but only when the user requires the switch terminal).
