net: mscc: ocelot: Register poll timeout should be wall time not attempts

2018-12-21T00:39:56Z

When doing indirect access in the Ocelot chip, a command is setup, issued and then we need to poll until the result is ready. The polling timeout is specified in milliseconds in the datasheet and not in register access attempts. It is not a bug on the currently supported platform, but we observed that the code does not work properly on other platforms that we want to support as the timing requirements there are different.

mscc: Configured MAC entries should be locked.

2018-12-21T00:22:45Z

The MAC table in Ocelot supports auto aging (normal) and static entries. MAC entries that is manually configured should be static and not subject to aging.

net: switchdev: Add extack to switchdev_handle_port_obj_add() callback

2018-12-13T00:34:22Z

Drivers use switchdev_handle_port_obj_add() to handle recursive descent through lower devices. Change this function prototype to take add_cb that itself takes an extack argument. Decode extack from switchdev_notifier_port_obj_info and pass it to add_cb. Update mlxsw and ocelot drivers which use this helper.

switchdev: Replace port obj add/del SDO with a notification

2018-11-24T02:02:24Z

Drop switchdev_ops.switchdev_port_obj_add and _del. Drop the uses of this field from all clients, which were migrated to use switchdev notification in the previous patches. Add a new function switchdev_port_obj_notify() that sends the switchdev notifications SWITCHDEV_PORT_OBJ_ADD and _DEL. Update switchdev_port_obj_del_now() to dispatch to this new function. Drop __switchdev_port_obj_add() and update switchdev_port_obj_add() likewise. Signed-off-by: Petr Machata Reviewed-by: Ido Schimmel Signed-off-by: David S. Miller

ocelot: Handle SWITCHDEV_PORT_OBJ_ADD/_DEL

2018-11-24T02:02:24Z

Following patches will change the way of distributing port object changes from a switchdev operation to a switchdev notifier. The switchdev code currently recursively descends through layers of lower devices, eventually calling the op on a front-panel port device. The notifier will instead be sent referencing the bridge port device, which may be a stacking device that's one of front-panel ports uppers, or a completely unrelated device. Dispatch the new events to ocelot_port_obj_add() resp. _del() to maintain the same behavior that the switchdev operation based code currently has. Pass through switchdev_handle_port_obj_add() / _del() to handle the recursive descend, because Ocelot supports LAG uppers. Register to the new switchdev blocking notifier chain to get the new events when they start getting distributed. Signed-off-by: Petr Machata Acked-by: Jiri Pirko Signed-off-by: David S. Miller
