From 45988dae4cf05f783e40e027c83594a9dc6551cd Mon Sep 17 00:00:00 2001 From: Joe Hershberger Date: Wed, 26 Sep 2018 16:49:00 -0500 Subject: test: eth: Add a test for ARP requests This tests that ARP requests made to this target's IP address are responded-to by the target when it is doing other networking operations. This currently corrupts the ongoing operation of the device if it happens to be awaiting an ARP reply of its own to whatever serverip it is attempting to communicate with. In the test, add an expectation that the user operation (ping, in this case) will fail. A later patch will address this problem.
