parentnet: sched: refactor block offloads counter usage (diff)
net: sched: notify classifier on successful offload add/delete
To remove dependency on rtnl lock, extend classifier ops with new ops->hw_add() and ops->hw_del() callbacks. Call them from cls API while holding cb_lock every time filter if successfully added to or deleted from hardware. Implement the new API in flower classifier. Use it to manage hw_filters list under cb_lock protection, instead of relying on rtnl lock to synchronize with concurrent fl_reoffload() call.
