Being 9 part of the kernel is currently best way to test the TX process of device driver 10 and NIC. pktgen can also be used to generate ordinary packets to test other 11 network devices. Especially of interest is the use of pktgen to test routers or 12 bridges which use the Linux network stack. Because pktgen is "in-kernel", it can 13 generate very high packet rates and with few systems saturate network devices as 14 routers or bridges. 15 """ 16 17 interface='eth0' 18 count=50000 19 20 # Parse comma-separated args. 21 for arg in args: 22 for item in arg.split(','): 23 key, val = item.split('=') 24 if key == 'interface': 25 interface = val 26 if key == 'count': 27 count = int(val) 28 if key == 'num_iterations': 29 num_iterations = int(val) 30 31 job.run_test('pktgen', eth=interface, count=count, clone_skb=0, 32 tag='clone_skb_off', num_iterations=num_iterations) 33 job.run_test('pktgen', eth=interface, count=count, clone_skb=1, 34 tag='clone_skb_on', num_iterations=num_iterations) 35 36
