Hi Lijun,

     The complete solution is to use a version with all of the fixes, as 
Anatoly suggested previously. I have just checked out the latest tip of 
the master branch, and l3fwd-power exits gracefully with a single CTRL-C:


...
Checking link statusdone
Port 0 Link Up - speed 100000 Mbps - full-duplex
L3FWD_POWER: entering main loop on lcore 27
L3FWD_POWER:  -- lcoreid=27 portid=0 rxqueueid=0
L3FWD_POWER: lcore 26 has nothing to do
L3FWD_POWER: lcore 27 sleeps until interrupt triggers
*^C*POWER: Power management governor of lcore 26 has been set back to  
successfully
POWER: Power management of lcore 26 has exited from 'performance' mode 
and been set back to the original
POWER: Power management governor of lcore 27 has been set back to

POWER: Power management of lcore 27 has exited from 'performance' mode 
and been set back to the original
