 The Kernel NIC Interface sample application is a simple example that demonstrates the use
 of the DPDK to create a path for packets to go through the Linux* kernel.
 This is done by creating one or more kernel net devices for each of the DPDK ports.
-The application allows the use of standard Linux tools (ethtool, ifconfig, tcpdump) with the DPDK ports and
