[ns] call-back from mac-802.11.cc to interface queue

[Behnaz Bostanipour]

Hi all,


As I checked in mac-802.11.cc, it seems that interface queue only sends one 
packet at a time to MAC 802.11 (but i am not 100% sure) and it waits to dequeue 
and send the next packet to 802.11 MAC until a callback is triggered by 
mac-802.11.

So the call back is triggered by mac-802.11 in tx_resume()

oid
Mac802_11::tx_resume()
{
        double rTime;
        assert(mhSend_.busy() == 0);
        assert(mhDefer_.busy() == 0);

        if(pktCTRL_) {
                ….              }
        } else if(pktTx_) {
        
….
                        }
                }
        } else if(callback_) {
                Handler *h = callback_;
                callback_ = 0;
                h->handle((Event*) 0);
        }
        setTxState(MAC_IDLE);

}

am I right?

Thanks,
Behnaz
