[ns] problem 'Scheduler ID is not valid'

[Claudio Cicconetti]

Your problem is that there is an event that is scheduled twice; this event
may be a timer expiration.

Try substituting

   if(pktCTRL_) {
      mhDefer_.start(phymib_.getSIFS());

with

   if(pktCTRL_) {
      if ( ! mhDefer_.busy() )
         mhDefer_.start(phymib_.getSIFS());

in the Mac802_11::tx_resume() method.

Regards
	Claudio
