# This test creates two netdevsim virtual interfaces, assigns one of them (the # "destination interface") to a new namespace, and assigns IP addresses to both # interfaces. # # It listens on the destination interface using socat and configures a dynamic # target on netconsole, pointing to the destination IP address. # # Finally, it checks whether the message was received properly on the # destination interface. Note that this test may pollute the kernel log buffer # (dmesg) and relies on dynamic configuration and namespaces being configured. # # Author: Breno Leitao <leitao@debian.org>
