Re: [PATCH net-next v3 4/9] net/sched: introduce flow_offload action cookie

Currently a hardware action is uniquely identified by the <id, hw_index>

cannot enforce this, and it is possible that a future change could break
this. In addition, <id, hw_index> are not unique across network namespaces.

Uniquely identify the action by setting an action cookie by the tc core.
Use the unique action cookie to query the action's hardware stats.
