Hi NS users,
I have a problem on getting a pointer to the link layer at the MAC.

I added the following to the Mac802_11::command(){
.....
else if(strcmp(argv[1], "up-target") == 0){
                       ll_ = (LL *) TclObject::lookup(argv[2]);
                       assert(ll_);
               }
       }
       return Mac::command(argc, argv);
}


The add-interface in ns-mobilenode.tcl says
$mac up-target $ll

I get a segfault, I wonder what went wrong. Any clue ??

Thanks
