Hi Stephen, Thanks for your reply, I was not aware of that. I am using 4-Port Intel 10Gigbit network card-> X710 for 10GbE, and this is currently bound to DPDK using VFIO-PCI driver, but the corresponding kernel network driver appears to be-> i40e.
Currently I dont see shared libraries built under DPDK's-> build/driver/net/i40e directory. Should I build those driver libraries, and then provide path to it, something like this in EAL param -> -d build/drivers/net/i40e/libi40e.so Please let me know.
