+      <p>The <tt>projects/routing</tt> Subversion branch is a
+	FreeBSD routing system rework aimed at providing performance,
+	scalability and the ability to add advanced features to the
+	routing stack.</p>
+
+      <p>Currently, the packet output path suffers from excessive
+	locking, acquiring and releasing 4 distinct contested locks is
+	required in order to convert a packet to a frame suitable to put
+	on the wire.  The first project goal is to reduce the number of
+	locks needed to just two <tt>rmlock(9)</tt>s for the output path,
+	which permits close-to-linear scaling.</p>
+
+      <p>Since September, one of the locks (used to protect
+	link-level entries) is completely eliminated from the packet data
+	path.  A new routing API was introduced, featuring better
+	scalability and hiding routing internals.  Most of the consumers
+	of the old routing API were converted to use the new API.</p>
