Does this actually require changing the main loop? If it really is the poll related changes that you mention it seems like they could be contained to the netdevs and userspace datapath. You could handle a batch of packets each time through the main loop. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
