 <li>Generic network stack improvements and bugfixes:
   <ul>
-	<li>Removed the direct ACK on every other data segment. After
-		receiving a data segment, we were sending out two ACKs, the first one
-		in tcp_input() direct after receiving and the second ACK after the
-		userland or the sosplice task read some data out of the socket buffer.
-		This change removes the ACK in tcp_input(), saving processing time and
-		improving network performance.
 	<li>Removed the maxburst feature from tcp_output().
+		Sending out TCP segments was limited to 4 packets per burst.
+		This did not scale well on high bandwith, high latency links.
+		Especially when the receiving side delays ACK packets
+		aggressively, the maxburst limitation could seriously reduce
+		TCP throughput per connection.
 	<li>Added a MONITOR feature to interfaces. Packets received on these
 		interfaces do not enter the network stack for further processing. This
 		can be used to watch traffic, for example with <a
