2018-11-28qede: Update link status only when interface is ready.Sudarsana Reddy Kalluru2-2/+7
In the case of internal reload (e.g., mtu change), there could be a race between link-up notification from mfw and the driver unload processing. In such case kernel assumes the link is up and starts using the queues which leads to the server crash. Send link notification to the kernel only when driver has already requested MFW for the link.

2018-11-28qede: Simplify the usage of qede-flags.Sudarsana Reddy Kalluru3-8/+11
The values represented by qede->flags is being used in mixed ways: 1. As 'value' at some places e.g., QEDE_FLAGS_IS_VF usage 2. As bit-mask(value) at some places e.g., QEDE_FLAGS_PTP_TX_IN_PRORGESS usage. This implementation pose problems in future when we want to add more flag values e.g., overlap of the values, overflow of 64-bit storage. Updated the implementation to go with approach (2) for qede->flags.

2018-11-28qed: Display port_id in the UFP debug messages.Sudarsana Reddy Kalluru1-7/+13
MFW sends UFP notifications mostly during the device init phase and PFs might not be assigned with a name by this time. Hence capturing port-id in the debug messages would help in finding which PF the ufp notification was sent to. Also, fixed a minor scemantic issue in a debug print.

2018-11-28mlxsw: spectrum: Flip driver to use emulated 802.1Q FIDsIdo Schimmel3-8/+10
Replace 802.1Q FIDs and VLAN RIFs with their emulated counterparts. The emulated 802.1Q FIDs are actually 802.1D FIDs and thus use the same flood tables, of per-FID type. Therefore, add 4K-1 entries to the per-FID flood tables for the new FIDs and get rid of the FID-offset flood tables that were used by the old 802.1Q FIDs.

2018-11-28mlxsw: spectrum_router: Introduce emulated VLAN RIFsIdo Schimmel1-0/+9
Router interfaces (RIFs) constructed on top of VLAN-aware bridges are of "VLAN" type, whereas RIFs constructed on top of VLAN-unaware bridges of "FID" type. In other words, the RIF type is derived from the underlying FID type. VLAN RIFs are used on top of 802.1Q FIDs, whereas FID RIFs are used on top of 802.1D FIDs. Since the previous patch emulated 802.1Q FIDs using 802.1D FIDs, this patch emulates VLAN RIFs using FID RIFs.

2018-11-28mlxsw: spectrum_fid: Introduce emulated 802.1Q FIDsIdo Schimmel1-0/+33
The driver uses 802.1Q FIDs when offloading a VLAN-aware bridge. Unfortunately, it is not possible to assign a VNI to such FIDs, which prompts the driver to forbid the enslavement of VxLAN devices to a VLAN-aware bridge. Workaround this hardware limitation by creating a new family of FIDs, emulated 802.1Q FIDs. These FIDs are emulated using 802.1D FIDs, which can be assigned a VNI. The downside of this approach is that multiple {Port, VID}->FID entries are required, whereas only a single VID->FID is required with "true" 802.1Q FIDs.

2018-11-28mlxsw: spectrum_fid: Make flood index calculation more robustIdo Schimmel1-1/+1
802.1D FIDs use a per-FID flood table, where the flood index into the table is calculated by subtracting 4K from the FID's index. Currently, 802.1D FIDs start at 4K, so the calculation is correct, but if it was ever to change, the calculation will no longer be correct. In addition, this change will allow us to reuse the flood index calculation function in the next patch, where we are going to emulate 802.1Q FIDs using 802.1D FIDs.

When configuring an FDB entry pointing to a LAG netdev (or its upper), the driver should only set the 'lag_vid' field when the FID (filtering identifier) is of 802.1D type. Extend the 802.1D FID family with an attribute indicating whether this field should be set and based on its value set the field or leave it blank.

2018-11-27net/mlx5: EQ, Introduce atomic notifier chain subscription APISaeed Mahameed3-3/+49
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.

2018-11-24rocker: Handle SWITCHDEV_PORT_OBJ_ADD/_DELPetr Machata1-0/+55
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. rocker currently doesn't support any uppers other than bridge. Thus the only case that a stacked device could be validly referenced by port object notifications are bridge notifications for VLAN objects added to the bridge itself. But the driver explicitly rejects such notifications in rocker_world_port_obj_vlan_add(). It is therefore safe to assume that the only interesting case is that the notification is on a front-panel port netdevice. Subscribe to the blocking notifier chain. In the handler, filter out notifications on any foreign netdevices. Dispatch the new notifiers to rocker_port_obj_add() resp. _del() to maintain the behavior that the switchdev operation based code currently has.
