Summary prefix should be just "ethdev: " and summary should
be human readable. It should not refer to defines etc.

I think that rte_flow_create() should check
the capability in !dev->data->dev_started case
and return error if capability is not advertised.
The only problem here is to avoid dev_info get on
each rte_flow_create() call.
There was no follow up to this patch.
Ori, could you give your opinion please?
