[ns] receive packet

[Kai Li]

Can someone explain when the mobilenode receive the packet,how does the packet 
pass from channel to the NetIF for the wireless channel?
>From my understanding, the transmitting node schedule a packet reception:

s.schedule(rifp,newp,propdelay) 

then after this I think somewhere  call NetIf->recv(..)(this network interface 
belongs to the reception node) but I can't find it. Thanks for any help..

ns version: ns-2.1b4 + cmu wireless extension

Kai,
