2024-09-13pmdomain: qcom-cpr: Use helper function for_each_available_child_of_node()Zhang Zekun
for_each_available_child_of_node() can help to iterate through the device_node, and we don't need to use while loop. Besides, the purpose of the while loop is to find a device_node which fits the condition "child_req_np == ref_np", we can just read the property of "child_np" directly in for_each_available_child_of_node(). No functional change with such conversion.

Roger Quadros says: ==================== net: ethernet: ti: am65-cpsw: Add multi queue RX support am65-cpsw can support up to 8 queues at Rx. So far we have been using only one queue (i.e. default flow) for all RX traffic. This series adds multi-queue support. The driver starts with 1 RX queue by default. User can increase the RX queues via ethtool, e.g. 'ethtool -L ethx rx <N>' The series also adds regmap and regfield support to some of the ALE registers. It adds Policer/Classifier registers and fields. Converting the existing ALE control APIs to regfields can be a separate exercise. Some helper functions are added to read/write to the Policer/Classifier registers and a default Classifier setup function is added that routes packets based on their PCP/DSCP priority to different RX queues.

2024-09-13net: ethernet: ti: cpsw_ale: add policer/classifier helpers and setup defaultsRoger Quadros
The Policer registers in the ALE register space are just shadow registers and use an index field in the policer table control register to read/write to the actual Polier registers. Add helper functions to Read and Write to Policer registers. Also add a helper function to set the thread value to classifier/policer mapping. Any packet that first matches the classifier will be sent to the thread (flow) that is set in the classifier to thread mapping table. If not set then it goes to the default flow. Default behaviour is to have 8 classifiers to map 8 DSCP/PCP priorities to N receive threads (flows). N depends on number of RX channels enabled for the port. As per the standard [1] User prioritie 1 (Background) and 2 (Spare) have lower priority than the user priority 0 (default). User priority 1 being of the lowest priority.

am65-cpsw can support up to 8 queues at Rx. Use a macro AM65_CPSW_MAX_RX_QUEUES to indicate that. As there is only one DMA channel for RX traffic, the 8 queues come as 8 flows in that channel. By default, we will start with 1 flow as defined by the macro AM65_CPSW_DEFAULT_RX_CHN_FLOWS. User can change the number of flows by ethtool like so 'ethtool -L ethx rx <N>' All traffic will still come on flow 0. To get traffic on different flows the Classifiers will need to be set up.

2024-09-13RDMA/mlx5: Use IB set_netdev and get_netdev functionsChiara Meiohas
The IB layer provides a common interface to store and get net devices associated to an IB device port (ib_device_set_netdev() and ib_device_get_netdev()). Previously, mlx5_ib stored and managed the associated net devices internally. Replace internal net device management in mlx5_ib with ib_device_set_netdev() when attaching/detaching a net device and ib_device_get_netdev() when retrieving the net device. Export ib_device_get_netdev(). For mlx5 representors/PFs/VFs and lag creation we replace the netdev assignments with the IB set/get netdev functions. In active-backup mode lag the active slave net device is stored in the lag itself. To assure the net device stored in a lag bond IB device is the active slave we implement the following: - mlx5_core: when modifying the slave of a bond we send the internal driver event MLX5_DRIVER_EVENT_ACTIVE_BACKUP_LAG_CHANGE_LOWERSTATE. - mlx5_ib: when catching the event call ib_device_set_netdev() This patch also ensures the correct IB events are sent in switchdev lag. While at it, when in multiport eswitch mode, only a single IB device is created for all ports. The said IB device will receive all netdev events of its VFs once loaded, thus to avoid overwriting the mapping of PF IB device to PF netdev, ignore NETDEV_REGISTER events if the ib device has already been mapped to a netdev.

Thus, remove this optimization and return the netdev even if it is undergoing unregistration, allowing matching by the caller.

2024-09-12net/mlx5: Add support for sync reset using hot resetMoshe Shemesh
On device that supports sync reset for firmware activate using hot reset, the driver queries the required reset method while handling the sync reset request. If the required reset method is hot reset, the driver will use pci_reset_bus() to reset the PCI link instead of the link toggle.

2024-09-12net/mlx5: fs, add support for no append at software levelMark Bloch
Native capability for some steering engines lacks support for adding an additional match with the same value to the same flow group. To accommodate the NO APPEND flag in these scenarios, we include the new rule in the existing flow table entry (fte) without immediate hardware commitment. When a request is made to delete the corresponding hardware rule, we then commit the pending rule to hardware. Only one pending rule is supported because NO_APPEND is primarily used during replacement operations. In this scenario, a rule is initially added. When it needs replacement, the new rule is added with NO_APPEND set. Only after the insertion of the new rule is the original rule deleted.
