Hi: I am new to DPDK and my current use case with DPDK is minimal. Thus, I think the l2fwd type of sample application should suffice.
Below is a portion of the output of `dpdk-devbind.py --status` command My DPDK version is 18.08, and I am using Ubuntu 16.04 (Linux Kernel version 4.15.12) Network devices using kernel driver =================================== 0000:01:00.0 'I350 Gigabit Network Connection 1521' if=eno1 drv=igb unused=igb_uio *Active* 0000:01:00.1 'I350 Gigabit Network Connection 1521' if=eno2 drv=igb unused=igb_uio 0000:81:00.0 'Ethernet Controller X710 for 10GbE SFP+ 1572' if=ens1f0 drv=i40e unused=igb_uio *Active* 0000:81:00.1 'Ethernet Controller X710 for 10GbE SFP+ 1572' if=ens1f1 drv=i40e unused=igb_uio *Active* I am connecting to this machine via 0000:01:00.0 My requirement is to be able to send packets from 0000:81:00.0 to 0000:81:00.1 and get some measurements like tx and rx times. I tried to run the sample app as (as shown in docs): ./l2fwd -n 1 -c f -- -q 8 -p 0x3 I have an error like this: EAL: Detected 16 lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: No free hugepages reported in hugepages-1048576kB EAL: No free hugepages reported in hugepages-1048576kB EAL: No free hugepages reported in hugepages-1048576kB EAL: Probing VFIO support...

Some inputs on this would be very helpful. Regards, Kushal.
