+Actions Performance
+-------------------
+
+Actions are used in OpenFlow flows to describe what to do when the flow
+matches a packet. Just like with the datapath interface, SIMD instructions
+can be applied to the action implementation to improve performance.
+
+OVS provides multiple implementations of the actions.
+Available implementations can be listed with the following command::
+
+    $ ovs-appctl dpif-netdev/action-impl-get
+        Available Actions implementations:
+            scalar (available: True, active: True)
+            autovalidator (available: True, active: False)
+            avx512 (available: True, active: False)
+
+By default, ``scalar`` is used.  Implementations can be selected by
+name::
+
+    $ ovs-appctl dpif-netdev/action-impl-set avx512
+    action implementation set to avx512.
+

 To run the OVS unit test suite with the autovalidator as the default
 implementation, it is required to recompile OVS.  During the recompilation,
 the default priority of the `autovalidator` implementation is set to the
 maximum priority, ensuring every test will be run with every implementation::
 
-    $ ./configure --enable-autovalidator --enable-mfex-default-autovalidator
+    $ ./configure --enable-autovalidator --enable-mfex-default-autovalidator \
+        --enable-actions-default-autovalidator
 
 The following line should be seen in the configuration log when the above
 options are used::
 
     checking whether DPCLS Autovalidator is default implementation... yes
     checking whether MFEX Autovalidator is default implementation... yes
+    checking whether actions Autovalidator is default implementation... yes
 
 Compile OVS in debug mode to have `ovs_assert` statements error out if
 there is a mis-match in the datapath classifier lookup or packet parser
