Here is the exact pkt-gen command line I'm using: - 60 byte Ethernet frame size (excluding the 4 CRC bytes) - 2000 UDP flows (20 IP sources * 100 IP destinations) pkt-gen -U -i igb2 -f tx -n 80000000 -l 60 -d 198.19.10.1:2000-198.19.10.20 -D 00:0d:b9:41:ca:3d -s 198.18.10.1:2000-198.18.10.100 -w 4 =E2=80=8BOption -U is available on a patched netmap version [1]: It fix the checksum calculation when using source/destination IP range on NIC that didn't enable HW CHKSUM in netmap mode and IPv6 support.
