Update of /cvsroot/tinyos/tinyos-2.x/tos/chips/cc2420
In directory sc8-pr-cvs10.sourceforge.net:/tmp/cvs-serv15669

Modified Files:
	CC2420ActiveMessageC.nc CC2420ActiveMessageP.nc 
Log Message:
Added the SendNotifier interface to support CTP + LPL integration.  

Create and drop a module into your system that listens for the SendNotifier events for the AM types related to CTP or Dissemination, then have it call LowPowerListening.setRxSleepInterval(msg, 512);.  Or capture the event for every AM type.

This can also be used to control other transmit parameters on a system-wide basis, like full duplex PA control on a per-destination basis, etc.  If this hook works out, we can expand this into other radio stacks.
