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 also extended with 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.

FWIW I applied these patches and they compiled, passed make check tests
and checkpatch.
