+Subject: [PATCH] Remove IAPP functionality from hostapd
+
+IEEE Std 802.11F-2003 was withdrawn in 2006 and as such it has not been
+maintained nor is there any expectation of the withdrawn trial-use
+recommended practice to be maintained in the future. Furthermore,
+implementation of IAPP in hostapd was not complete, i.e., only parts of
+the recommended practice were included. The main item of some real use
+long time ago was the Layer 2 Update frame to update bridges when a STA
+roams within an ESS, but that functionality has, in practice, been moved
+to kernel drivers to provide better integration with the networking
+stack.
