parentnet: sched: extend proto ops with 'put' callback (diff)
net: sched: extend proto ops to support unlocked classifiers
Add 'rtnl_held' flag to tcf proto change, delete, destroy, dump, walk functions to track rtnl lock status. Extend users of these function in cls API to propagate rtnl lock status to them. This allows classifiers to obtain rtnl lock when necessary and to pass rtnl lock status to extensions and driver offload callbacks. Add flags field to tcf proto ops. Add flag value to indicate that classifier doesn't require rtnl lock. Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
