+	  This option makes it possible to send different netlink messages
+	  to tasks depending on whether the task is a compat task or not. To
+	  achieve this, you need to set skb_shinfo(skb)->frag_list to the
+	  compat skb before sending the skb, the netlink code will sort out
+	  which message to actually pass to the task.
+
+	  Newly written code should NEVER need this option but do
+	  compat-independent messages instead!
