> Tunnel Offload API provides hardware independent, unified model
> to offload tunneled traffic. Key model elements are:
>  - apply matches to both outer and inner packet headers
>    during entire offload procedure;
>  - restore outer header of partially offloaded packet;
>  - model is implemented as a set of helper functions.
> 
> Implementation details:
> * tunnel_offload PMD parameter must be set to 1 to enable the feature.
> * application cannot use MARK and META flow actions whith tunnel.
> * offload JUMP action is restricted to steering tunnel rule only.
