+Date:           Oct 2013
+Contact:        haver@linux.vnet.ibm.com
+Description:    Default VF timeout 250ms. Testing might require 1000ms.
+                Using 0 will use the cards default value (whatever that is).
+
+                The timeout depends on the max number of available cards
+                in the system and the maximum allowed queue size.
+
+                The driver ensures that the settings are done just before
+                the VFs get enabled. Changing the timeouts in flight is not
+                possible.
+                Only available for PF.
