    samples: pktgen: add trap SIGINT for printing execution result · 6c882bdc
    Juhee Kang authored
    All pktgen samples can send indefinitely num messages per thread by
    setting the count option to 0(-n 0). If running sample with setting
    count 0 and press Ctrl-C to stop this program, the program prints the
    result of the execution so far. Currently, the samples besides
    sample{3...5} don't work properly. Because Ctrl-C stops the script, not
    just pktgen.
    
    This is results of samples:
    
        # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample04_many_flows.sh -n 0
        Running... ctrl^C to stop
        ^CDevice: eth0@0
        Result: OK: 569657(c569538+d118) usec, 84650 (60byte,0frags)
        148597pps 71Mb/sec (71326560bps) errors: 0
    
        # DEV=eth0 DEST_IP=10.1.0.1 DST_MAC=00:11:22:33:44:55 ./pktgen_sample01_simple.sh -n 0
        Running... ctrl^C to stop
        ^C
    
    In order to solve this, this commit adds trap SIGINT. Also, this commit
    changes control_c function to print_result to maintain consistency with
    other samples.
