Abstract
A loopback test of the datalink layer of a network interface device is performed from a user-space software layer. In certain embodiments, network address translation rules in the network layer are modified to change source and destination network addresses of a test packet to a fake IP address, to enable the test packet to be forwarded from the network layer to the datalink layer.
