Introduce raw-encap and raw-decap actions. The two actions are added in command line options, and for the data to encap or decap the user need to parse it within the command line. All values of raw-encap data is set to be fixed values. Usage example: --raw-encap=ether,ipv4,udp,vxlan Signed-off-by: Wisam Jaddo <wisamm@mellanox.com> Acked-by: Alexander Kozyrev <akozyrev@nvidia.com>
