> Subject: [PATCH v5] tunneling: Avoid recirculation on datapath by computing
> the recirculate actions at translate time.
> 
> 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.
