+  Open vSwitch is a production quality, multilayer, software-based, Ethernet
+  virtual switch. It is designed to enable massive network automation through
+  programmatic extension, while still supporting standard management interfaces
+  and protocols (e.g. NetFlow, sFlow, SPAN, RSPAN, CLI, LACP, 802.1ag). In
+  addition, it is designed to support distribution across multiple physical
+  servers similar to VMware's vNetwork distributed vswitch or Cisco's Nexus
+  1000V.

+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.
