+Subject: [PATCH] ifupdown: pass interface device name for ipv6 route commands
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+IPv6 routes need the device argument for link-local routes, or they
+cannot be used at all. E.g. "gateway fe80::def" seems to be used in
+some places, but kernel refuses to insert the route unless device
+name is explicitly specified in the route addition.
