In that case, in the software model, the packet is switched. Thus when offloading mirroring like that, take into consideration FDB, STP, PVID configured at the bridge, and whether that VLAN ID should be tagged on egress. Patch #1 introduces functions to get bridge PVID, VLAN flags and to look up an FDB entry. Patches #2 and #3 refactor some existing code and introduce a new accessor function. With patches #4 and #5 mlxsw calls mlxsw_sp_span_respin() on switchdev events as well. There is no impact yet, because bridge as an underlay device is still not allowed. That is implemented in patch #6, which uses the new interfaces to figure out on which one port the mirroring should be configured, and whether the mirrored packets should be VLAN-tagged and how. Changes from v2 to v3: - Rename the suite of bridge accessor function to br_vlan_get_pvid(), br_vlan_get_info() and br_fdb_find_port(). The _get bit is to avoid clashing with an existing static function. Changes from v1 to v2: - Change the suite of bridge accessor functions to br_vlan_pvid_rtnl(), br_vlan_info_rtnl(), br_fdb_find_port_rtnl(). ==================== Signed-off-by: David S.
