samples: pktgen: add trap SIGINT for printing execution result
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. Signed-off-by: Juhee Kang <claudiajkang@gmail.com> Signed-off-by: David S.
