I am still not sure what is the best solution here.
I continued to think about it in this thread:
	http://mails.dpdk.org/archives/dev/2019-November/151960.html

I think we cannot require any application change until 20.11
in order to keep API (and behaviour) compatibility.
If something would be implemented in 20.02,
it must be a new and optional API.
That's why I think no deprecation notice is required.

[...]
> +* ethdev: New offload flag ``DEV_RX_OFFLOAD_FLOW_MARK`` will be added in 20.02.
> +  This will provide application an information if ``RTE_FLOW_ACTION_TYPE_MARK``
