+From 709063e8368aeed56fd5775c10d33ca4dc8990a5 Mon Sep 17 00:00:00 2001

+Subject: [PATCH] ipaddress: accept symbolic names
+Organization: Addiva Elektronik
+
+The function rtnl_addproto_a2n() was defined but never used.
+Use it to allow for symbolic names, and fix the function signatures
+so protocol value is consistently __u8.
