[ns] Add a wired interface to a wireless node

[Sankaran Sriram]

Hello ns-users,

  Does anyone know how to add a wired interface to pairs of wireless
nodes so that they can communicate using the wired interface. I
searched online and found the add-interface command but I guess it is
primarily for creating more wireless interfaces for wireless nodes.

  Your help would be greatly appreciated.

Thanks
Sriram
