+ <body>
+ <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>
