Maybe I'm missing something but I don't see that you added the ability to match on any
of the header fields value.
You also didn't update the code of encap (from my understanding this is a tunnel header)

Hi Ori,
This feature is only support for iavf enable PPPoL2TPv2oUDP rss. So it doesn't need to add the ability to match on any of the header fields value and the code of encap.
I'm not sure if it is necessary to add these.

You added a lot of fields in the rte_flow and you don't give any way to test them.
also Iike I said in previous patch what is the relation between matching items to RSS?
You didn't add it to the RSS possible support.

The feature apply a RSS rule on L2TP data packet (include PPP over L2TP) with inner IP / port as input set.
It doesn't need match any L2TP field.

Just to be clear when you say RSS on mean RSS on ipv4+udp for example not on the ppp header itself right?
If so then the title should just state that you are adding new items (also for other patches)
since I can use this item to jump to other group or count or any other action. This patch dosesn't have anything to do with hash.
I understand that from your point of view you don't need to match on any field, but you added such fields and no one
can test it and no PMD support this so this feature is not valid.

Ori
