Open vSwitch supports flow-based control at a level that is much more fine-grained than L2. There's no guarantee that the L2 information alone will tell you where the packet needs to go. RSS spreads processing and interrupts based on a hash, which is supported. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
