+Subject: [PATCH 2/2] netdev-linux: Let interface flag survive internal port
+ setup
+
+Due to a race condition when bringing up an internal port on Linux
+some interface flags (e.g. IFF_MULTICAST) are falsely reset. This
+happens because netlink events may be processed after the according
+netdev has been brought up (which sets interface flags).
+
+Fix this by reading the interface flags just before updating them
+if they have not been updated by from the kernel yet.
