<div class="Bd Pp Bd-indent"><code class="Cd">device miibus</code>

<p class="Pp">The <code class="Nm">lge</code> driver provides support for
various NICs based on the Level 1 LXT1001 NetCellerator Gigabit Ethernet
controller chip.</p>
<p class="Pp">The LXT1001 supports fiber PHYs and also a GMII port for use with
10/100/1000 copper PHYs, however there are currently no NICs on the market
that use this feature.</p>
<p class="Pp">The LXT1001 supports TCP/IP checksum offload for receive and
VLAN-based filtering as well as a 64-bit multicast hash filter. It also
supports jumbo frames, which can be configured via the interface MTU
setting. Selecting an MTU larger than 1500 bytes with the
<a class="Xr">ifconfig(8)</a> utility configures the adapter to receive and
transmit jumbo frames. Using jumbo frames can greatly improve performance
for certain tasks, such as file transfers and data streaming.</p>
<p class="Pp">The <code class="Nm">lge</code> driver supports the following
media types:</p>
<dl class="Bl-tag">
<dt id="autoselect"><a class="permalink" href="#autoselect"><code class="Cm">autoselect</code></a></dt>
<dd>Enable autoselection of the media type and options. The user can manually
override the autoselected mode by adding media options to
<a class="Xr">rc.conf(5)</a>.</dd>
<dt id="1000baseSX"><a class="permalink" href="#1000baseSX"><code class="Cm">1000baseSX</code></a></dt>
<dd>Set 1000baseSX operation over fiber optic cable. Both
<code class="Cm">full-duplex</code> and
<code class="Cm">half-duplex</code> modes are supported.</dd>
</dl>
<p class="Pp">The <code class="Nm">lge</code> driver supports the following
media options:</p>
<dl class="Bl-tag">
<dt id="full-duplex"><a class="permalink" href="#full-duplex"><code class="Cm">full-duplex</code></a></dt>
<dd>Force full duplex operation.</dd>
<dt id="half-duplex"><a class="permalink" href="#half-duplex"><code class="Cm">half-duplex</code></a></dt>
<dd>Force half duplex operation.</dd>
