MoonGen is a fully scriptable high-speed packet generator built on DPDK and LuaJIT. It can saturate a 10 Gbit/s connection with 64 byte packets on a single CPU core while executing user-provided Lua scripts for each packet. Multi-core support allows for even higher rates. It also features precise and accurate timestamping and rate control.

Could not configure device 0: error Invalid argument #260

Hi, I am trying to run MoonGen with IntelDPDK 18.11, and this is what I am getting

The same command run with IntelDPDK 17.08 results in the correct output. I understand that 18.11 may not be supported, but can someone give me a hint why am I having the issue?

We unfortunately cannot support most DPDK versions because we need ABI-compatibility (and some optional custom patches), this looks like a case of an ABI mismatch.
