Openvswitch datapath recirculates packets for tunneling, i.e. the incoming packets are encapsulated at first pass. Further actions are applied on encapsulated packets on the second pass after recirculating. The proposed patch compute and append the post tunnel actions at the time of translation itself instead of recirculating at datapath. These actions are solely depends on tunnel attributes so there is no need of datapath recirculation. By avoiding the recirculation at datapath, the patch offers upto 30% performance improvement for VxLAN tunneling in our testing. The action execution logic is using the new CLONE action to define the packet cloning when the actions are combined. The lenght in the CLONE action specifies the size of nested action set.
It also fixing the test suites failures that are introduced by nested CLONE action in tunneling. v5 - Fix the OVN test case failure by commenting the test validation as its not relevant with the new tunnel CLONE action. - Code changes for applying CLONE action on a batch than individual packets are already pushed to the master. V5 patch is now only doing CLONE at tunnel push. v4 - Rename the function to compute post tunnel nested function. - Use the clone action syntax itself for the flow display. - Use nl_msg functions for handling the nested attribute. - Modify the CLONE action to process packets in batch than individually. v3 - Rebase with newely clone action and use it for tunneling. v2 - Use only single CLONE action with length to mark the tunnel combine action set. - Update the datapath trace display functions to handle CLONE. - Fixed test cases to work with CLONE action.
