* net/mlx5: Split the activate lag function into two routinesRoi Dayan2018-12-141-4/+10

* IB/mlx5: Unify e-switch representors load approach between uplink and VFsMark Bloch2018-12-143-22/+19
| | | | | | | | | | | | | | | When in switchdev mode and the add function is called by the core level driver, make sure we only register the callbacks, but don't create the mlx5 IB device or initialize anything. With this change all the IB devices in switchdev mode are created only once the load callback is invoked by the e-switch core sub-module. This follows the design paradigm under which the all the Eth representors must be loaded before any of IB reprs is loaded.

| | | | | | | | | | | | | | | Update the flow steering command formatting according to the extended destination API. Note that the FW dictates that multi destination FTEs that involve at least one encap must use the extended destination format, while single destination ones must use the legacy format. Using extended destination format requires FW support. Check for its capabilities and return error if not supported.

| | | | | | | | | | | | | | | | | | | | | | | | Remove the deprecated mlx5_interface->event mlx5_ib callback and use new mlx5 notifier API to subscribe for mlx5 events. For native mlx5_ib devices profiles pf_profile/nic_rep_profile register the notifier callback mlx5_ib_handle_event which treats the notifier context as mlx5_ib_dev. For vport repesentors, don't register any notifier, same as before, they didn't receive any mlx5 events. For slave port (mlx5_ib_multiport_info) register a different notifier callback mlx5_ib_event_slave_port, which knows that the event is coming for mlx5_ib_multiport_info and prepares the event job accordingly. Before this on the event handler work we had to ask mlx5_core if this is a slave port mlx5_core_is_mp_slave(work->dev), now it is not needed anymore. mlx5_ib_multiport_info notifier registration is done on mlx5_ib_bind_slave_port and de-registration is done on mlx5_ib_unbind_slave_port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use atomic_notifier_chain to fire firmware events at internal mlx5 core components such as eswitch/fpga/clock/FW tracer/etc.., this is to avoid explicit calls from low level mlx5_core to upper components and to simplify the mlx5_core API for future developments. Simply provide register/unregister notifiers API and call the notifier chain on firmware async events. Example: to subscribe to a FW event: struct mlx5_nb port_event; MLX5_NB_INIT(&port_event, port_event_handler, PORT_CHANGE); mlx5_eq_notifier_register(mdev, &port_event); where: - port_event_handler is the notifier block callback. - PORT_EVENT is the suffix of MLX5_EVENT_TYPE_PORT_CHANGE. The above will guarantee that port_event_handler will receive all FW events of the type MLX5_EVENT_TYPE_PORT_CHANGE. To receive all FW/HW events one can subscribe to MLX5_EVENT_TYPE_NOTIFY_ANY. The next few patches will start moving all mlx5 core components to use this new API and cleanup mlx5_eq_async_int misx handler from component explicit calls and specific logic.
