+      <p>An update to the &os; RDMA stack based on code from Linux
+	v4.9 was merged into &os; 12-CURRENT on November 4th,
+	including many bug fixes and new features with a focus on
+	RoCEv2 — Routable RoCE.</p>
+
+      <p>RDMA over Converged Ethernet (RoCE) is a network protocol
+	that leverages Remote Direct Memory Access (RDMA) capabilities
+	to accelerate communications between applications hosted on
+	clusters of servers and storage arrays.  RoCE incorporates the
+	IBTA RDMA semantics to allow devices to perform direct memory
+	to memory transfers at the application level without involving
+	the host CPU.  Both the transport processing and the memory
+	translation and placement are performed by hardware resulting
+	in lower latency, higher throughput, and better performance
+	compared to software based protocols.</p>
+
+      <p>RoCEv2 is the most recent version of RoCE, adding some routing
+	capabilities as both IP and UDP headers are included in the
+	packet format.  To complete the RoCEv2 solution, Support for
+	ECN (Explicit Congestion Notification, lossy fabric) and PFC
+	(Priority Flow Control, lossless fabric) protocols with rate
+	limiting options will be added in the first quarter of
+	2018.</p>
+
+      <p>This project also introduces the following updates:</p>
+
+      <ul>
+	<li><tt>libibverbs</tt>, <tt>librdmacm</tt>,
+	  <tt>libibumad</tt> and vendor-specific libraries
+	  ported from the Linux rdma-core v15+</li>
+
+	<li>InfiniBand diagnostic tools,
+	  <tt>infiniband-diags</tt>, version 1.6.7</li>
+
+	<li>InfiniBand subnet manager — OpenSM, version 3.3.20+</li>
+
+	<li>LinuxKPI support</li>
+      </ul>
+
+      <p>Important notes:</p>
+
+      <ul>
+	<li>GPL-only (non dual-licensed) portions of the Linux code were either
+	excluded or written from scratch under a BSD license by
+	&a.hselasky;.</li>
+
+	<li>The code has been tested by several RDMA vendors
+	  that also support iWARP.</li>
+      </ul>
