[ns] Help: address of an agent's associated node

[Madhu Hosaagrahara]

Hello,
        I've written a class that derives from Tap (defined in ~ns/mac/ 
mac.h) and I've managed to have it associated with the mac object and  
listen to objects promiscuously.
        My question is how do I get the address of the node with which this  
Tap is associated?
Thanks,
~Madhu.
