</links>
<body>
<p>A new driver, <tt>cxgbei</tt>, that enables hardware
accelerated iSCSI with Chelsio's T5- and T4-based offload-capable
cards, has been committed to HEAD. Both Initiator and Target are
supported. The wire traffic is standard iSCSI (SCSI over TCP as
per RFC 3720, etc.) so an Initiator/Target using this driver will
interoperate with all other standards-compliant
implementations.</p>
<p>Hardware assistance provided by the T5 and T4 ASICs includes:</p>
<ul>
<li>Complete TCP processing.</li>
<li>iSCSI PDU identification and extraction from the byte
oriented TCP stream.</li>
<li>Header and/or data digest generation and
verification.</li>
<li>Zero copy support for both transmit and receive.</li>
</ul>

<p>The <tt>cxgbei(4)</tt> man page is missing but will be
committed shortly.</p>

<p>The driver is in advanced stage QA and will see some
bugfixes and performance enhancements in the very near future.
MFC is possible as soon as the QA cycle completes.</p>
