No. > Can you briefly let me know why the design was kept so ? It's not possible to do in a general and efficient manner. The flows kept by the kernel are significantly simpler than the ones in userspace to make them easier to process. The consequence is that they are less expressive and you can potentially need a lot more of them to cover the entire space, which is prohibitively expensive. _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss
