[RFC 0/2] queue-based flow aged report

[Xiaoyu Min <jackmin@nvidia.com>]

For the queue-based flow managemnt, application can operate the same flow
on the same queue.

For example, application create flow with age action, query aged flow,
and destroy aged flow. All operations of flow happens on the same queue.

In this case, the PMD could be more optimized since all operations of the
same flow happens in sequence.

The current flow aged report API hasn't queue parameter as same as other
queue-based flow management API.

This RFC propose to add new flow aged report API with queue parameter.
Keep the old one for compatibility.

v2:
  - Add new API for querying which queues have aged out flows instead of
    passing queue id via *ret_param* in event.
  - Use bit flags instead of enum
  - Fix typo and wording

Xiaoyu Min (2):
  ethdev: port flags for pre-configuration flow hints
  ethdev: queue-based flow aged report
