+Q: What Linux kernel versions does each Open vSwitch release work with?
+
+A: The following table lists the Linux kernel versions against which the
+   given versions of the Open vSwitch kernel module will successfully
+   build.  The Linux kernel versions are upstream kernel versions, so
+   modified Linux kernels modified from the upstream sources may not
+   build in some cases even if they are based on a supported version.
+   This is most notably true of Red Hat Enterprise Linux (RHEL) kernels,
+   which are extensively modified from upstream.
+
+   Open vSwitch   Linux kernel
+   ------------   -------------
+       1.4.x      2.6.18 to 3.2
+       1.5.x      2.6.18 to 3.2
+       1.6.x      2.6.18 to 3.2
+       1.7.x      2.6.18 to 3.3
+       1.8.x      2.6.18 to 3.4
+       1.9.x      2.6.18 to 3.7
+
+   Open vSwitch userspace should also work with the Linux kernel module
+   built into Linux 3.3 and later.
+
+   Open vSwitch userspace is not sensitive to the Linux kernel version.
+   It should build against almost any kernel, certainly against 2.6.18
+   and later.

 Q: What features are not available in the Open vSwitch kernel datapath
    that ships as part of the upstream Linux kernel?
 
 A: The kernel module in upstream Linux 3.3 and later does not include
    the following features:
 
-       - Bridge compatibility, that is, support for the ovs-brcompatd
-         daemon that (if you enable it) lets "brctl" and other Linux
-         bridge tools transparently work with Open vSwitch instead.
-
-         We do not expect bridge compatibility to ever be available in
-         upstream Linux.  If you need bridge compatibility, use the
-         kernel module from the Open vSwitch distribution instead of the
-         upstream Linux kernel module.
-
        - Tunnel virtual ports, that is, interfaces with type "gre",
          "ipsec_gre", "capwap".  It is possible to create tunnels in
          Linux and attach them to Open vSwitch as system devices.
