Hi Yuan,
Some comments are inline. Please change the naming format of test case and remove some reductant outputs from the plan.
Thanks,

> +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.

> + So, in driver layer, we can begin to support the new ones and remove
> + the old ones.

> + 2. testpmd > show port <port_id> rx_offload configuration
> + 3. testmpd > port config <port_id> rx_offload <offload> on|off

Suggest to remove the useless spaces in the description.

Please use code name NNT replace of 82599. Since this test plan only cover FVL and NNT hardware, please update "support list file" in following patches.

> +Notes: There is different capabilities between i40e and ixgbe.

I'd like to add NNT in the title, rename case name like "NNT Rx offload per-queue setting".

Too much details in the test plan may make it not easy to catch the main point.
Comment like 'Queue 2 should capture strip vlan information like "VLAN tci=0x1" and "PKT_RX_VLAN_STRIPPED"' is enough.

Description about CRC_STRIP and KEEP_CRC is more like note.
