| * | | | mlxsw: spectrum: Add missing flood to router portIdo Schimmel2016-08-24

The following packet types are mirrored: * DHCP: Broadcast packets that should be flooded by the device, but also trapped in case CPU is running the DHCP server. * IGMP query: Multicast packets that need to be forwarded to other bridge ports, but also trapped so that receiving netdev will be marked as a router port by the bridge driver. * ARP request: Broadcast packets that should be forwarded to other bridge ports, but also trapped in case requested IP is of the local machine. * ARP response: Unicast packets that should be forwarded by the bridge but also trapped in case response is directed at us. Set the trap action of such packets to mirror and mark them using 'offload_fwd_mark' to prevent the bridge driver from forwarding them itself. Note that OSPF packets are also marked despite their action being trap. The reason for this is that the device traps such packets in the pipeline after they were already flooded.

Since these vPorts were used for slow path traffic we had to disable learning for them, as it doesn't make sense to have it enabled. This is no longer the case and now vPorts are either used for router interfaces (for which learning is disabled by the firmware) or bridge ports (for which learning is explicitly enabled by the driver). Therefore, we can remove the learning configuration upon vPort creation. Signed-off-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

However, this is sub-optimal in cases where learning is disabled on the bridge port, as the device repeatedly generates learning notifications for the same record. Instead, offload the learning configuration to the device, thereby preventing it from generating notifications when learning is disabled.

This turned out to be problematic in situations where a large number of MACs (48K) had to be processed by the switch driver, as RTNL mutex is held during the learning session. Instead, limit the number of FDB records that can be processed in a session to 64. This means that every time the device is queried for learning notifications (currently, every 100ms), up to 64 records will be processed by the switch driver.

From Saeed, ten patches that refactors old layouts of firmware commands which were manually generated before we introduced the mlx5_ifc, now all of the firmware commands inbox/outbox layouts moved to use mlx5_ifc and we remove the old manually generated structures. Plus to those ten patches, we add two patches that unifies mlx5 commands execution interface and improve the driver log messages in that area. From Hadar and Ilya, added the needed hardware bits and infrastructure for minimum inline headers setting and encap/decap commands and capabilities, needed for E-Switch offloads. This series applies on top latest net-next and rdma/master, and smoothly merges with the latest "Mellanox 100G mlx5 fixes 2016-08-16" series already applied into net branch. ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now as all commands use mlx5 ifc interface, instead of doing two calls for executing a command we embed command status checking into mlx5_cmd_exec to simplify the interface. Also we do here some cleanup for redundant software structures (inbox/outbox) and functions and improved command failure output.

| * | {net,IB}/mlx5: Modify QP commands via mlx5 ifcSaeed Mahameed2016-08-17

In ConnectX-4 for each QP transition there is a specific command and their layout can vary. e.g: 2err/2rst commands don't have QP context in their layout and before this patch we posted the QP context in those commands. Fortunately the FW only checks the suffix of the commands and executes them, while ignoring all invalid data sent after the valid command layout. This patch removes mlx5_modify_qp_mbox_in and changes mlx5_core_qp_modify to receive the required transition and QP context with opt_param_mask if needed. This way the caller is not required to provide the command inbox layout and it will be generated automatically. mlx5_core_qp_modify will generate the command inbox/outbox layouts according to the requested transition and will fill the requested parameters.
