<p class="Pp">The <code class="Nm">msk</code> device driver provides support for
various NICs based on the Marvell/SysKonnect Yukon II Gigabit Ethernet
controller chip.</p>
<p class="Pp">All NICs supported by the <code class="Nm">msk</code> driver have
TCP/UDP/IP checksum offload for transmit, TCP segmentation offload (TSO),
hardware VLAN tag stripping/insertion features and an interrupt moderation
mechanism as well as a 64-bit multicast hash filter. The Yukon II supports
TBI (ten bit interface) and GMII transceivers, which means it can be used
with either copper or 1000baseX fiber applications.</p>
<p class="Pp">The Yukon II also supports Jumbo Frames (up to 9022 bytes), 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.</p>
<p class="Pp">The <code class="Nm">msk</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="10baseT/UTP"><a class="permalink" href="#10baseT/UTP"><code class="Cm">10baseT/UTP</code></a></dt>
<dd>Set 10Mbps operation. The <a class="Xr">ifconfig(8)</a>

modes.</dd>
<dt id="100baseTX"><a class="permalink" href="#100baseTX"><code class="Cm">100baseTX</code></a></dt>

modes.</dd>
<dt id="1000baseTX"><a class="permalink" href="#1000baseTX"><code class="Cm">1000baseTX</code></a></dt>
<dd>Set 1000baseTX operation over twisted pair. The

<dt id="1000baseSX"><a class="permalink" href="#1000baseSX"><code class="Cm">1000baseSX</code></a></dt>

<code class="Cm">full-duplex</code> and

</dl>
<p class="Pp">The <code class="Nm">msk</code> driver supports the following
