Device support: Intel E810, Found 0 usable devices:

Hi!
I have run MoonGen on Intel 82599 NIC successfully, but I meet some problems when I use 100Gbps Intel E810-CQDA2 NIC.
I bind igb_uio driver on two ports of this card and run the basic script to test it (sudo ./build/MoonGen examples/l3-load-latency.lua 0 1).
But MoonGen can't find available ports.
Here is the output: (Note that 0000:5e:00.0 and 0000:5e:00.1 are Intel 82599 NICs)

Does MoonGen support Intel E810-CQDA2?

I have the same issue. Have you tried using dpdk directly with the E810 @magaboomchen ? That's my next step.

Hi, intel e810 supports DPDK, and I run the DPDK applications using intel E810 successfully.
As far as I know, e810 needs DPDK's version above 19.02.
So, I also try the Moongen branch dpdk-19.05 but it also fails to find the device.
Intel E810 is a new NIC, and I suspect that we may need to modify some part of the source code of Moongen to support E810.

Hi! I am having the same issue with a Intel I225-V.

Have you solve this problem??
