<p class="Pp">NOTE: This driver has not been ported from
    <span class="Ux">4.4BSD</span> yet.</p>
<p class="Pp">The <code class="Nm">ex</code> interface provides access to a 10
    Mb/s Ethernet network through an Excelan controller used as a link-layer
    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">ex</code> interface employs the address resolution protocol
    described in <a class="Xr">arp(4)</a> to dynamically map between Internet
    and Ethernet addresses on the local network.</p>
