Generate traffic such that interested network peers are aware of
<em class="parameter"><code>dev</code></em>, such as by generating a gratuitous ARP. This may be used when
a device wants to inform the rest of the network about some sort of
reconfiguration such as a failover event or virtual machine
migration.
