Saeed Mahameed says: ==================== mlx5-updates-2023-02-10 1) From Roi and Mark: MultiPort eswitch support MultiPort E-Switch builds on newer hardware's capabilities and introduces a mode where a single E-Switch is used and all the vports and physical ports on the NIC are connected to it. The new mode will allow in the future a decrease in the memory used by the driver and advanced features that aren't possible today. This represents a big change in the current E-Switch implantation in mlx5. Currently, by default, each E-Switch manager manages its E-Switch. Steering rules in each E-Switch can only forward traffic to the native physical port associated with that E-Switch. While there are ways to target non-native physical ports, for example using a bond or via special TC rules. None of the ways allows a user to configure the driver to operate by default in such a mode nor can the driver decide to move to this mode by default as it's user configuration-driven right now. While MultiPort E-Switch single FDB mode is the preferred mode, older generations of ConnectX hardware couldn't support this mode so it was never implemented. Now that there is capable hardware present, start the transition to having this mode by default. Introduce a devlink parameter to control MultiPort Eswitch single FDB mode. This will allow users to select this mode on their system right now and in the future will allow the driver to move to this mode by default. 2) From Jiri: Improvements and fixes for mlx5 netdev's devlink logic 2.1) Cleanups related to mlx5's devlink port logic 2.2) Move devlink port registration to be done before netdev alloc 2.3) Create auxdev devlink instance in the same ns as parent devlink 2.4) Suspend auxiliary devices only in case of PCI device suspend * tag 'mlx5-updates-2023-02-10' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: Suspend auxiliary devices only in case of PCI device suspend net/mlx5: Remove "recovery" arg from mlx5_load_one() function net/mlx5e: Create auxdev devlink instance in the same ns as parent devlink net/mlx5e: Move devlink port registration to be done before netdev alloc net/mlx5e: Move dl_port to struct mlx5e_dev net/mlx5e: Replace usage of mlx5e_devlink_get_dl_port() by netdev->devlink_port net/mlx5e: Pass mdev to mlx5e_devlink_port_register() net/mlx5: Remove outdated comment net/mlx5e: TC, Remove redundant parse_attr argument net/mlx5e: Use a simpler comparison for uplink rep net/mlx5: Lag, Add single RDMA device in multiport mode net/mlx5: Lag, set different uplink vport metadata in multiport eswitch mode net/mlx5: E-Switch, rename bond update function to be reused net/mlx5e: TC, Add peer flow in mpesw mode net/mlx5: Lag, Control MultiPort E-Switch single FDB mode ==================== Link: https://lore.kernel.org/r/20230214221239.159033-1-saeed@kernel.orgSigned-off-by: Jakub Kicinski <kuba@kernel.org>
