<p class="Pp">The <code class="Nm">arswitch</code> driver provides a management
    interface to Atheros AR8000 series Ethernet switch controllers. The driver
    uses an <a class="Xr">mdio(4)</a> or <a class="Xr">miibus(4)</a> interface
    to configure the ethernet interface.</p>
<p class="Pp">This driver supports port based vlan, and IEEE 802.1Q (QinQ).
    These options can be configured with the <a class="Xr">etherswitchcfg(8)</a>
    command. <code class="Nm">arswitch</code> supports
    <code class="Dv">addtag</code>, <code class="Dv">striptag</code>, and
    <code class="Dv">doubletag</code>. <code class="Dv">addtag</code> and
    <code class="Dv">striptag</code> are mutually exclusive.</p>
