In the current process, the multicast MAC is added to both MAC_VLAN table and MTA table, this will reduce the utilization of the resource. This patch improves the process of adding multicast MAC address, the new process starts using the MTA table to add multicast MAC after the MAC_VLAN table is full, and the MTA is disable if it is no longer used.

when skb->encapsulation is 0, skb->ip_summed is CHECKSUM_PARTIAL and it is udp packet, which has a dest port as the IANA assigned. the hardware is expected to do the checksum offload, but the hardware will not do the checksum offload when udp dest port is 4789.

When hardware sends the HCLGE_VECTOR0_EVENT_RST event through hclge_misc_irq_handle, currently driver enables misc_vector in the interrupt handle, and hardware generates the same interrupt for the same reset event again and again until the reset is complete, which causes hclge_reset running repeatly problem.

Petr Machata says: ==================== Test mirror-to-gretap with bridge in UL This patchset adds more tests to the mirror-to-gretap suite where bridge is present in the underlay. Specifically it adds tests for bridge VLAN handling, FDB, and bridge port STP status. In patches #1-#3, the codebase is refactored to support the new tests. In patch #4, an STP test is added to the mirroring library, that will later be called from bridge tests. In patches #5-#8, the test for mirror-to-gretap with an 802.1q bridge in underlay is adapted and more tests are added. In patch #9, an STP test is added to the test suite for mirror-to-gretap with an 802.1d bridge in underlay. ==================== Signed-off-by: -

Offloading of mirror-to-gretap in mlxsw is tricky especially in cases when the gretap underlay involves bridges. Add more tests that exercise the bridge handling code: - forbidden_egress tests that check vlan removal on bridge port in the underlay packet path - untagged_egress tests that similarly check "egress untagged" - fdb_roaming tests that check whether learning FDB on a different port is reflected - stp tests for handling port STP status of bridge egress port Signed-off-by:

As the mvpp2 driver is growing, move this driver to a dedicated directory and split it into several files. Since this driver has a lot of register defines and structure definitions, it can benefit from having all of this into a dedicated header file, named mvpp2.h. A good chunk of the mvpp2 code is dedicated to Header Parser handling, so we introduce mvpp2_prs.h where all Header Parser definitions are located, and mvpp2_prs.c containing the related code. In the same way, mvpp2_cls.h and mvpp2_cls.c are created to contain Classifier and RSS related code. The former 'mvpp2.c' file is renamed 'mvpp2_main.c' so that we can keep the driver binary named 'mvpp2'. This commit is only about spliting the driver into multiple files and doesn't introduce any new function, feature or fix besides removing 'static' keywords when needed. Signed-off-by:

tc_ctl_tfilter handles three netlink message types: RTM_NEWTFILTER, RTM_DELTFILTER, RTM_GETTFILTER. However, implementation of this function involves a lot of branching on specific message type because most of the code is message-specific. This significantly complicates adding new functionality and doesn't provide much benefit of code reuse. Split tc_ctl_tfilter to three standalone functions that handle filter new, delete and get requests. The only truly protocol independent part of tc_ctl_tfilter is code that looks up queue, class, and block. Refactor this code to standalone tcf_block_find function that is used by all three new handlers. Signed-off-by:

In the quest to remove all stack VLA usage from the kernel[1], this allocates the maximum size expected for all possible types and adds sanity-checks at both registration and usage to make sure nothing gets out of sync. This matches the proposed VLA solution for nfnetlink[2]. The values chosen here were based on finding assignments for .maxtype and .slave_maxtype and manually counting the enums: slave_maxtype (max 33): IFLA_BRPORT_MAX 33 IFLA_BOND_SLAVE_MAX 9 maxtype (max 45): IFLA_BOND_MAX 28 IFLA_BR_MAX 45 __IFLA_CAIF_HSI_MAX 8 IFLA_CAIF_MAX 4 IFLA_CAN_MAX 16 IFLA_GENEVE_MAX 12 IFLA_GRE_MAX 25 IFLA_GTP_MAX 5 IFLA_HSR_MAX 7 IFLA_IPOIB_MAX 4 IFLA_IPTUN_MAX 21 IFLA_IPVLAN_MAX 3 IFLA_MACSEC_MAX 15 IFLA_MACVLAN_MAX 7 IFLA_PPP_MAX 2 __IFLA_RMNET_MAX 4 IFLA_VLAN_MAX 6 IFLA_VRF_MAX 2 IFLA_VTI_MAX 7 IFLA_VXLAN_MAX 28 VETH_INFO_MAX 2 VXCAN_INFO_MAX 2 This additionally changes maxtype and slave_maxtype fields to unsigned, since they're only ever using positive values.

Petr Machata says: ==================== net: bridge: Notify about bridge VLANs In commit 946a11e7 ("mlxsw: spectrum_span: Allow bridge for gretap mirror"), mlxsw got support for offloading mirror-to-gretap such that the underlay packet path involves a bridge. In that case, the offload is also influenced by PVID setting of said bridge. However, changes to VLAN configuration of the bridge itself do not generate switchdev notifications, so there's no mechanism to prod mlxsw to update the offload when these settings change. In this patchset, the problem is resolved by distributing the switchdev notification SWITCHDEV_OBJ_ID_PORT_VLAN also for configuration changes on bridge VLANs. Since stacked devices distribute the notification to lower devices, such event eventually reaches the driver, which can determine whether it's a bridge or port VLAN by inspecting orig_dev. To keep things consistent, the newly-distributed notifications observe the same protocol as the existing ones: dual prepare/commit, with -EOPNOTSUPP indicating lack of support, even though there's currently nothing to prepare for and nothing to support. Correspondingly, all switchdev drivers have been updated to return -EOPNOTSUPP for bridge VLAN notifications. In patches #1 and #2, the code base is changed to support the following additions: functions br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del() are introduced to simplify sending notifications; and br_vlan_add_existing() is introduced to later make it simpler to add error-handling code for the case of configuring a preexisting VLAN on bridge CPU port. In patches #3-#6, respectively for mlxsw, rocker, DSA and DPAA2 ethsw, the new notifications (which are not enabled yet) are ignored to maintain the current behavior. In patch #7, the notification is actually enabled. In patch #8, mlxsw is changed to update offloads of mirror-to-gre also for bridge-related notifications. Changes from v3 to v4: - In patch #1, separate variable declarations from program logic. - Add patch #2. - In patch #7, add error handling around a newly-introduced call to br_switchdev_port_vlan_add(). - Rephrase commit messages of patches #3-#6 to explain motivation for the change. Changes from v2 to v3: - Add a fallback definition for br_switchdev_port_obj_add() and br_switchdev_port_obj_del() when !CONFIG_NET_SWITCHDEV. Changes from v1 to v2: - Rename br_switchdev_port_obj_add() and br_switchdev_port_obj_del() to br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del(), and move from br_vlan.c to br_switchdev.c. ==================== Signed-off-by:

Since there's no special support for the bridge events, the driver returns -EOPNOTSUPP, and thus the commit never happens. Therefore schedule respin during the prepare stage: there's no real difference one way or another. This fixes the problem that mirror-to-gretap offload wouldn't adapt to changes in bridge vlan configuration right away and another notification would have to arrive for mlxsw to catch up.

A driver might need to react to changes in settings of brentry VLANs. Therefore send switchdev port notifications for these as well. Reuse SWITCHDEV_OBJ_ID_PORT_VLAN for this purpose. Listeners should use netif_is_bridge_master() on orig_dev to determine whether the notification is about a bridge port or a bridge. Signed-off-by:

A follow-up patch enables emitting VLAN notifications for the bridge CPU port in addition to the existing slave port notifications. These notifications have orig_dev set to the bridge in question. Because there's no specific support for these VLANs, just ignore the notifications to maintain the current behavior. Signed-off-by:
