> +PMD drivers adaption for new RXTX offload APIs
> +==============================================
> +Description
> +===========
> +
> + Adapt all the Intel drivers for the new RX/TX offload APIs.
> + There're new RX/TX offload APIs accepted in 17.11,
> + These new APIs are more friendly and easier to use.
> + Currently, they co-exist with the old APIs. Some adaption work is
> + here to make the drivers can use the old ones or the new ones.
> + But suppose the target is to let all the NICs support the new APIs
> + and then remove the old ones.
> + So, in driver layer, we can begin to support the new ones and remove
> + the old ones.
> + Eight new commands are added.
