new CLI part is side effect of the rte_flow, to demonstrate how to use
flow modes. I was more interested in how much change required in
rte_flow header.

Is this is referring previous push back for rte_filter_type update, I
think this can be evaluated case by case. As far as I remember
previously it is rejected in favor of improving rte_flow, this time
update is required to be able to use rte_flow, so I assume can be OK.
I believe this can be discussed out of this patch scope.
> By now, rte_flow has no support for rss config application, but only filter configuration. But maybe this can be a work in next release.
At least it is good that this effort can be re-used later for rte_flow,
I still believe this option worth investigating for further releases.
