This program type can set skb hash value. It will be useful

You've ignored the feedback and just resend? what for?

No, I do not. Some patches did not reach relevant people at all, so I
just resent _all_ the patches to all the people.
I will copy your earlier comment to this patch and will address it in
the discussion.
Sorry for misunderstanding and some redundant noise.
