Newer generation Hardware uses the slightly different port speed bit widths, so alter the existing port speed bit range to extend support to the newer generation hardware while maintaining the backward compatibility with older generation hardware. The previously reserved bits are now being used which then requires the adjustment to the BIT values, e.g.: Before: PORT_PROPERTY_0[22:21] - Reserved PORT_PROPERTY_0[26:23] - Supported Speeds After: PORT_PROPERTY_0[21] - Reserved PORT_PROPERTY_0[26:22] - Supported Speeds To make this backwards compatible, the existing BIT definitions for the port speeds are incremented by one to maintain the original position.

Horatiu Vultur says: ==================== net: lan966x: Add switchdev and vlan support This patch series extends lan966x with switchdev and vlan support. The first patches just adds new registers and extend the MAC table to handle the interrupts when a new address is learn/forget. v7->v8: - remove extra mac learn when the port leaves the bridge - replace memcpy with ether_addr_copy - change the order of operations in lan966x_switch_driver_init/exit - refactor lan966x_port_bridge_flags v6->v7: - fix build issues when compiling as a module v5->v6: - fix issues with the singletones, they were not really singletons - simplify the case where lan966x ports are added to bridges with foreign ports - drop the cases NETDEV_PRE_UP and NETDEV_DOWN - fix the change of MAC address - drop the callbacks .ndo_set_features, .ndo_vlan_rx_add_vid, .ndo_vlan_rx_kill_vid - remove duplicate code when port was added in a vlan, the MAC entries will be added by the fdb v4->v5: - make the notifier_block from lan966x to be singletones - use switchdev_handle_port_obj_add and switchdev_handle_fdb_event_to_device when getting callbacks in the lan966x - merge the two vlan patches in a single one v3->v4: - split the last patch in multiple patches - replace spin_lock_irqsave/restore with spin_lock/spin_unlock - remove lan966x_port_change_rx_flags because it was copying all the frames to the CPU instead of removing all RX filters. - implement SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS - remove calls to __dev_mc_unsync/sync as they are not needed - replace 0/1 with false/true - make sure that the lan966x ports are not added to bridges that have other interfaces except lan966x - and allow the lan966x ports to be part of only the same bridge. v2->v3: - separate the PVID used when the port is in host mode or vlan unaware - fix issue when the port was leaving the bridge v1->v2: - when allocating entries for the mac table use kzalloc instead of devm_kzalloc - also use GFP_KERNEL instead of GFP_ATOMIC, because is never called in atomic context - when deleting an mac table entry, the order of operations was wrong - if ana irq is enabled make sure it gets disabled when the driver is removed ==================== Signed-off-by:David S.

This patch adds basic support to offload in the HW the forwarding of the frames. The driver registers to the switchdev callbacks and implements the callbacks for attributes SWITCHDEV_ATTR_ID_PORT_STP_STATE and SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME.

Beside the test event ('MLXSW_REG_MFDE_EVENT_ID_TEST') that is triggered following the devlink health 'test' sub-command, the new events are used to report the triggering of asserts in firmware code ('MLXSW_REG_MFDE_EVENT_ID_FW_ASSERT') and hardware issues ('MLXSW_REG_MFDE_EVENT_ID_FATAL_CAUSE').

Commit 0a6890b9 ("bnx2x: Utilize FW 7.13.15.0.") added validation for fastpath HSI versions for different client init which was not meant for SR-IOV VF clients, which resulted in firmware asserts when running VF clients with different fastpath HSI version. This patch along with the new firmware support in patch #1 fixes this behavior in order to not validate fastpath HSI version for the VFs. Fixes: 0a6890b9 ("bnx2x: Utilize FW 7.13.15.0.")

Simon Horman says: ==================== allow user to offload tc action to net device Baowen Zheng says: Allow use of flow_indr_dev_register/flow_indr_dev_setup_offload to offload tc actions independent of flows. The motivation for this work is to prepare for using TC police action instances to provide hardware offload of OVS metering feature - which calls for policers that may be used by multiple flows and whose lifecycle is independent of any flows that use them. This patch includes basic changes to offload drivers to return EOPNOTSUPP if this feature is used - it is not yet supported by any driver.

Tony Nguyen says: ==================== 40GbE Intel Wired LAN Driver Updates 2021-12-17 Brett Creeley says: This patch series adds support in the iavf driver for communicating and using VIRTCHNL_VF_OFFLOAD_VLAN_V2. The current VIRTCHNL_VF_OFFLOAD_VLAN is very limited and covers all 802.1Q VLAN offloads and filtering with no granularity. The new VIRTCHNL_VF_OFFLOAD_VLAN_V2 adds more granularity, flexibility, and support for 802.1ad offloads and filtering. This includes the VF negotiating which VLAN offloads/filtering it's allowed, where VLAN tags should be inserted and/or stripped into and from descriptors, and the supported VLAN protocols. ==================== Signed-off-by: -
