For DPDK bonding to work the application must call TX routines even when idle, Pktgen did not do this in older versions.

Now Pktgen does work with bonding driver and I have been using it for a few week now. Please have a look at the current version of Pktgen. should be a 3.1.0 version on master.

What is the version you are using now?

Here is a command line I used to for 8 port/ 2 bonds of 4 ports each.

./app/app/x86_64-native-linuxapp-gcc/app/pktgen -l 1-3,18-19 -n 4 --proc-type auto --log-level 8 --socket-mem 4096,4096 --file-prefix pg --vdev=net_bonding0,mode=4,xmit_policy=l23,slave=0000:04:00.0,slave=0000:04:00.1,slave=0000:04:00.2,slave=0000:04:00.3 --vdev=net_bonding1,mode=4,xmit_policy=l23,slave=0000:81:00.0,slave=0000:81:00.1,slave=0000:81:00.2,slave=0000:81:00.3 -b 05:00.0 -b 05:00.1 -b 82:00.0 -b 83:00.0 -- -T -P --crc-strip -m [2:3].0 -m [18:19].1 -f themes/black-yellow.theme
