+      <p>Building on the new in-kernel iSCSI initiator stack released
+	in &os; 10.0 and the recently added iSCSI offload interface,
+	Mellanox Technologies has begun developing iSCSI extensions
+	for RDMA (iSER) initiator support to enable efficient data
+	movement using the hardware offload capabilities of Mellanox's
+	10, 40, 56 and 100 gigabit IB/Ethernet adapters.</p>
+
+      <p>Remote Direct Memory Access (RDMA) have been shown to have a
+	great value for storage applications.  RDMA infrastructure
+	provides benefits such as Zero-Copy, CPU offload, Reliable
+	transport, Fabric consolidation, and many more.  The iSER
+	protocol eliminates some of the bottlenecks in the traditional
+	iSCSI/TCP stack, provides low latency and high throughput, and
+	is well suited for latency aware workloads.</p>
+
+      <p>This work includes a new ICL module that implements the iSER
+	initiator.  The iSCSI stack is slightly modified to support
+	some extra features such as asynchronous IO completions,
+	unmapped data buffers, and data-transfer offloads.  The user
+	will be able to choose iSER as the iSCSI transport with
+	<tt>iscsictl</tt>.</p>
+
+      <p>The project is in its beta phase.  Recent additions
+	include:</p>
+
+      <ul>
+	<li>Rebased on top of 11-CURRENT (r284921)</li>
+	<li>Added discovery over iSER support</li>
+	<li>HA and automatic session re-establishment support</li>
+	<li>Split iSER from iSCSI module</li>
+      </ul>
+
+      <p>In addition, the <tt>iser</tt> driver has been and continues
+	to be thoroughly tested.  The test suite includes:</p>
+
+      <ul>
+	<li>traffic</li>
+	<li>FS tests</li>
+	<li>compliance tests</li>
+	<li>traffic failover/failback</li>
+	<li>session recovery</li>
+	<li>dynamic module load/unload</li>
+      </ul>
+
+      <p>The code is ready for inclusion and will be released under
+	the BSD license.</p>
