>In tunnels packet there can be two UDP headers:
>- outer which for hw should be mark as ICE_UDP_OF
>- inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if
>  inner header is of TCP type
>
>In none tunnels packet header can be:
>- UDP, which for hw should be mark as ICE_UDP_ILOS
>- TCP, which for hw should be mark as ICE_TCP_IL
>
>Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS.
>ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to error
>from hw while adding this kind of recipe.
>
>In summary, for tunnel outer port type should always be set to ICE_UDP_OF,
>for none tunnel outer and tunnel inner it should always be set to
>ICE_UDP_ILOS.
