+    @param sw_if_index - The interface the RA prefix information is for

+    @param address_length - the prefix length
+    @param use_default - Revert to default settings
+    @param no_advertise - Do not advertise this prefix
+    @param off_link - The prefix is off link (it is not configured on the interface)
+                      Configures the L-flag, When set, indicates that this
+		      prefix can be used for on-link determination.
+    @param no_autoconfig - Setting for the A-flag. When
+                           set indicates that this prefix can be used for
+                          stateless address configuration.
+    @param no_onlink - The prefix is not on link. Make sure this is consistent
+                       with the off_link parameter else YMMV

+                     (0xffffffff) represents infinity
