[ns] How to install Tap agents in mobilenodes

[<zhanping@ece.ubc.ca>]

In the ns manual on Mobile Networking:
Tap Agents: 
Agents that subclass themselves as Tap../ns-2/mac.h defined in mac.h can 
register themselves with the mac object using method installTap(). If the 
particular Mac protocol permits it, the tap will promiscuously be given all 
packets received by the mac layer, before address filtering is done. See 
mac.{cc,h} for Tap implementation. 

Does anyone try this before? Is the MAC 802.11 supports Tap agents. I try 
to useing Tap in wired-cmu-wireless scenario, is it works for mobile nodes?

Thanks.
