Hi,

System settings: VM

Error message I got upon build: 


# ~/Documents/Pktgen-DPDK$ make

./tools/pktgen-build.sh build

Also I've got dpdk testpmd running problem as well:

When you get a message like no-ports it normally means the port is not bound to DPDK via dpdk-devbind.py or DPDK can not find a driver to support the NIC device. DPDK loads a set of drivers at startup (which can be a limited set of drivers) and if that driver is not what you need it will give no ports found. You can load extra drivers via DPDK command line or Pktgen command line or you can look in the pktgen/app/Makefile to see if your driver is loaded. This could also mean the NIC type is not supported even if the correct driver is loaded. This would be a DPDK driver problem and CX6 is most likely not found or supported.

Also the Ubuntu version 18.04 is pretty old and my not be supported by DPDK.
