Hi  Stephen,

I did rebind the NIC's to vfio-pci using the 

dpdk-devbind.py script.

Does that mean both the NICs (I219-LM and I1210) are not supported by DPDK?

Thanks,

Aniket Singh

You have to rebind the NIC's to vfio-pci to allow use by DPDK.
Did you look at dpdk-devbind.py script?

Also, some of the on board Ethernet controllers are not yet supported
by DPDK. They fall under the igb driver, but the PCI id's are not listed.
Needs backport from BSD or Linux driver for that.
