Subject: [patch net-next v4 01/10] flow_offload: Introduce offload of HW stats type

From: Jiri Pirko <jiri@...lanox.com>

Initially, pass "ANY" (struct is zeroed) to the drivers as that is the
current implicit value coming down to flow_offload. Add a bool
indicating that entries have mixed HW stats type.

---
v3->v4:
- fixed member alignment
v2->v3:
- moved to bitfield
- removed "mixed" bool
v1->v2:
- moved to actions
- add mixed bool
