Pravin B Shelar says: ==================== Open vSwitch Following batch of patches brings feature parity between upstream ovs and out of tree ovs module. Two features are added, first adds support to export egress tunnel information for a packet. This is used to improve visibility in network traffic. Second feature allows userspace vswitchd process to probe ovs module features. Other patches are optimization and code cleanup. ====================
