Comment(by jcardona):

 Network Manager needs to be off while capturing.  Corrected:

 {{{
 SECS=30
 CAPTURE_FILE=`date +%y%m%d%H%M`.cap
 TRAFFIC_MASK=0x7

 echo Capturing traffic for $SECS seconds...
 killall NetworkManager
 sleep 1
 echo $TRAFFIC_MASK > /sys/class/net/msh0/device/libertas_rtap
 ifconfig rtap0 up
 tcpdump -s 128 -i rtap0 -w $CAPTURE_FILE &> /dev/null &
 PID=$!
 sleep $SECS
 kill $PID
 echo Done.  Capture file is $CAPTURE_FILE
 NetworkManager
 }}}
