<p class="Pp">All versions of the EtherLink XL (except the older 3c900 and
3c905) support IPv4/TCP/UDP checksumming in hardware. The
<code class="Nm">ex</code> driver supports this feature of the chip. See
<a class="Xr">ifconfig(8)</a> for information on how to enable this
feature.</p>

<h1 class="Sh" id="MEDIA_SELECTION"><a class="permalink" href="#MEDIA_SELECTION">MEDIA
SELECTION</a></h1>
<p class="Pp">Some of these network interfaces support the Media Independent
Interface (MII), a bus which can have at least one arbitrary Physical
interface (PHY) chip on it. <span class="Ux">NetBSD</span> supports MII and
has separate drivers for many different PHY chips, including
<a class="Xr">ukphy(4)</a>, a generic PHY driver that can support many PHY
chips that <span class="Ux">NetBSD</span> does not yet have a specific
driver for.</p>
<p class="Pp">Support for the PHY found on a given NIC must be configured into a
<span class="Ux">NetBSD</span> kernel <a class="Xr">config(1)</a> for this
driver to work properly in those cases.</p>
