[ns] forwarding mcast packets

[Per Olesen <polesen@nordija.com>]

Hi,

I have a problem forwarding IP multicast packets from a multicast classifier. 
In my classifier, I determine which next hop(s) that should receive the 
packet. The next hop is identified by a node id and OTcl name.

Then I do a lookup on the node name using TclObject::lookup() and then I call 
recv(pkt) on the reference returned.

But the packet never seems to reach its destination (nothing seems to happen).
I do this, with the packet I forward:

      Packet* packetCopy = pkt->copy();

      hdr_cmn->prev_hop_ = node_id_; // node id of forwarding node
      hdr_cmn->next_hop_ = nextnodeid; //node id of next hop node
      hdr_cmn->addr_type() = NS_AF_INET; 
      hdr_cmn->direction() = hdr_cmn::DOWN;

      next->recv(packetCopy, hndl);

What could I be doing wrong?
