<p class="Pp">The <code class="Nm">liquidio</code> driver provides support for
23XX 10Gb/25Gb Ethernet adapters. The driver supports Jumbo Frames,
Transmit/Receive checksum offload, TCP segmentation offload (TSO), Large
Receive Offload (LRO), VLAN tag insertion/extraction, VLAN checksum offload,
VLAN TSO, and Receive Side Steering (RSS)</p>
<p class="Pp">Support for Jumbo Frames is provided 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. The maximum MTU size for Jumbo Frames is 16000.</p>
<p class="Pp">For more information on configuring this device, see
ifconfig(8).</p>
