One more thing, I think this flag should be added now since you need
it, I think you should report that you don't support it.
since just like we talked there is no real difference between metadata and MARK.
What do you think?

It sounds like a trick :) Negative support is *not* a support in fact. DPDK policy
requires support of a feature in a PMD and in-tree application. Of course, it is
not a problem to add meta. It is really easy to do. I just don't want to add it in
v5 to be deleted in v6 because of my above concerns.

This was not a trick. I understand what you are saying.
if we say that metadata is the same as mark, (I think we all agree on it) and that
application need to notify pmd about such operations, I assume it will try to see how to
request the metadata.

Frankly speaking I feel sick when I think about META and MARK
together. Do we really need both in DPDK?

I'm O.K. with adding it later and in any case I promise you that if you add it
it will stay.

Many thanks, I see.
