Hi Kushal, The output of dpdk-devbind -- status that you posted shows that there are no ports that are bound to dpdk. This is the reason for the error you get. You should try insmod igb_uio.ko ( this kernel module is generated in the build process of DPDK)
And dpdk-devbind.py -b igb_uio 0000:81:00.0 And likewise to the other port, 0000:81:00.1 And the launch the l2fwd app. You can also use vfio-pci or uio_pci_generic for binding the device to DPDK, look in the docs.
