When the uplink representors are put into lag, set all the representors (VFs and uplinks) of the same NIC to return the same switchdev id. Currently, the route lookup code on the encapsulation offload path assumes that same switchdev id for the source and dest devices means that the dest is also mlx5 HW netdev. This doesn't hold anymore when we align the switchdev Id of the uplinks to be same, which in turn causes the bond/team to return that id to the caller. As such, enhance the relevant check to take into account the uplink lag case.

Assign a counter dev attribute according to device capability and use it for management of counters related to offloaded eswitch TC flows. With upcoming support for uplink LAG, we have two HW rules per one logical SW (TC) rule. Although the HW supports attaching one counter to multiple rules, we are allocating counter per HW rule. We need this separation for two reasons: 1. "flow eswitch" counter affinity HW require the counter to be allocated on the device where the eswitch rule is set. 2. for some use-cases (multi-path routing) each HW flow relates to different neighbour, hence our neigh update logic must have a per-rule HW accountant in order to provide the proper feedback to the kernel.

Under uplink LAG or multipath schemes, traffic that matches one flow might arrive on both uplink ports and transmitted through both as part of supporting aggregation and high-availability. To cope with the fact that the SW model might use logical SW port (e.g uplink team or bond) but we have two HW ports with e-switch on each, there are cases where in order to offload a SW TC rule we need to duplicate it to two HW flows. Since each HW rule has its own counter we also aggregate the counter of both rules when a flow stats query is executed from user-space. Introduce the changes for the different elements (add/delete/stats), currently nothing is duplicated.

In the sriov offloads mode, packets that are not matched by any other rule are sent towards the e-switch vport manager for further processing. Under upcoming patches (e.g for uplink LAG), packets sent from VF vports belonging to esw0 (e-switch related to PF0) might end up in esw1 (e-switch related to PF1) due to muxing logic applied by the FW. In such a case we still want the missed packet to be sent to the "base" esw manager vport in order to present the control plane a consistent view of the source (VF reresentor) port.

This dictates the device affinity for eswitch flow counters, set by the FW according to the HW device capabilities. Under "source eswitch" affinity, the counter should be allocated on the device related to the source vport in the match. This covers both non merged e-switch mode as well as old FW that does not advertise this cap. Under "flow eswitch" affinity, the counter should be allocated on the device where the eswitch rule is set.

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.

Petr Machata says: ==================== Introduce NETDEV_PRE_CHANGEADDR Spectrum devices have a limitation that all router interfaces need to have the same address prefix. In Spectrum-1, the requirement is for the initial 38 bits of all RIFs to be the same, in Spectrum-2 the limit is 36 bits. Currently violations of this requirement are not diagnosed. At the same time, if the condition is not upheld, the mismatched MAC address ends up overwriting the common prefix, and all RIF MAC addresses silently change to the new prefix. It is therefore desirable to be able at least to diagnose the issue, and better to reject attempts to change MAC addresses in ways that is incompatible with the device. Currently MAC address changes are notified through emission of NETDEV_CHANGEADDR, which is done after the change. Extending this message to allow vetoing is certainly possible, but several other notification types have instead adopted a simple two-stage approach: first a "pre" notification is sent to make sure all interested parties are OK with the change that's about to be done. Then the change is done, and afterwards a "post" notification is sent. This dual approach is easier to use: when the change is vetoed, nothing has changed yet, and it's therefore unnecessary to roll anything back. Therefore this patchset introduces it for NETDEV_CHANGEADDR as well. One prominent path to emitting NETDEV_CHANGEADDR is through dev_set_mac_address(). Therefore in patch #1, give this function an extack argument, so that a textual reason for rejection (or a warning) can be communicated back to the user. In patch #2, add the new notification type. In patch #3, have dev.c emit the notification for instances of dev_addr change, or addition of an address to dev_addrs list. In patches #4 and #5, extend the bridge driver to handle and emit the new notifier. In patch #6, change IPVLAN to emit the new notifier. Likewise for bonding driver in patches #7 and #8. Note that the team driver doesn't need this treatment, as it goes through dev_set_mac_address(). In patches #9, #10 and #11 adapt mlxsw to veto MAC addresses on router interfaces, if they violate the requirement that all RIF MAC addresses have the same prefix. Finally in patches #12 and #13, add a test for vetoing of a direct change of a port device MAC, and indirect change of a bridge MAC. ==================== Signed-off-by: David S.

When a port is attached to a bridge, the address of the bridge in question may change as well. Even if it would not change at this point (because the current bridge address is lower), it might end up changing later as a result of detach of another port, which can't be vetoed. Therefore issue NETDEV_PRE_CHANGEADDR regardless of whether the address will be used at this point or not, and make sure all involved parties would agree with the change.

Petr Machata says: ==================== Pass extack to SWITCHDEV_PORT_OBJ_ADD Drivers may need to do validation as a result of port object addition. An example is mlxsw, which needs to check the configuration of a VXLAN device attached to an offloaded bridge. Without a mapped VLAN, the invalidity of the device is not important, but as soon as a pvid, untagged VLAN is configured for the device, it has to be validated and offloaded. Should the validation fail, there's currently no way to communicate details of the failure to the user, beyond an error number. Because currently, extack is not available at all in that area of code, this patch starts down at the RTNL level and progresses up towards the driver(s). In patch #1, ndo_bridge_setlink is updated to include extack, and callbacks of all clients are updated as well (ignoring the argument). In patch #2, the bridge driver is updated to propagate the extack through to the switchdev border, br_switchdev_port_vlan_add(). Patches #3, #4 and #5 then gradually extend switchdev to pass the extack argument through to the switchdev blocking notifier chain. Patches #6 and #7 then update mlxsw to pass the extack argument from VXLAN events resp. port events on to mlxsw_sp_bridge_8021q_vxlan_join(). Finally in patches #8 and #9, the code paths from the previous two patches are verified to yield an error message. v2: - Patch #1: - In ndo_bridge_setlink(), keep the whole extack declaration on the same line. ==================== Signed-off-by: David S.
