<p class="Pp">The <code class="Nm">enic</code> interface provides access to an
    Ethernet network via the eMIPS builtin eNIC (Extensible Network Interface
    Controller - Ethernet) interface.</p>
<p class="Pp">Each of the host's network addresses is specified at boot time
    with an <code class="Dv">SIOCSIFADDR</code> <a class="Xr">ioctl(2)</a>. The
    <code class="Nm">enic</code> interface employs the Address Resolution
    Protocol (ARP) described in <a class="Xr">arp(4)</a> to dynamically map
    between Internet and Ethernet addresses on the local network.</p>
<p class="Pp">Multicast Ethernet frames are unconditionally received and must be
    filtered in software.</p>
