Re: [ns] ns Qs (fwd)

The lan node object is indexed independent of the node id. 
its specified in the class Mac int index_ variable. 

The recv function of the mac identifies the direction of the packet based
on the presence of a handle. If there is a handle then the packet is
outgoing else its incoming. The ns manual section 13.5.3 has more
information on it.
