A port netdev is the software representation of +the physical port and provides a conduit for control traffic to/from the +controller (the kernel) and the network, as well as an anchor point for higher +level constructs such as bridges, bonds, VLANs, tunnels, and L3 routers. Using +standard netdev tools (iproute2, ethtool, etc), the port netdev can also +provide to the user access to the physical properties of the switch port such +as PHY link state and I/O statistics. + +There is (currently) no higher-level kernel object for the switch beyond the +port netdevs. All of the switchdev driver ops are netdev ops or switchdev ops. + +A switch management port is outside the scope of the switchdev driver model. +Typically, the management port is not participating in offloaded data plane and +is loaded with a different driver, such as a NIC driver, on the management port +device. + +Port Netdev Naming +^^^^^^^^^^^^^^^^^^ + +Udev rules should be used for port netdev naming, using some unique attribute +of the port as a key, for example the port MAC address or the port PHYS name. +Hard-coding of kernel netdev names within the driver is discouraged; let the +kernel pick the default netdev name, and let udev set the final name based on a +port attribute. + +Using port PHYS name (ndo_get_phys_port_name) for the key is particularly +useful for dynamically-named ports where the device names its ports based on +external configuration. For example, if a physical 40G port is split logically +into 4 10G ports, resulting in 4 port netdevs, the device can give a unique +name for each port using port PHYS name. The udev rule would be: + +SUBSYSTEM=="net", ACTION=="add", DRIVER="<driver>", ATTR{phys_port_name}!="", \ + NAME="$attr{phys_port_name}" + +Suggested naming convention is "swXpYsZ", where X is the switch name or ID, Y +is the port name or ID, and Z is the sub-port name or ID. For example, sw1p1s0 +would be sub-port 0 on port 1 on switch 1. + +Switch ID +^^^^^^^^^ + +The switchdev driver must implement the switchdev op switchdev_port_attr_get +for SWITCHDEV_ATTR_PORT_PARENT_ID for each port netdev, returning the same +physical ID for each port of a switch. The ID must be unique between switches +on the same system. The ID does not need to be unique between switches on +different systems. + +The switch ID is used to locate ports on a switch and to know if aggregated +ports belong to the same switch. + +Port Features +^^^^^^^^^^^^^ + +NETIF_F_NETNS_LOCAL + +If the switchdev driver (and device) only supports offloading of the default +network namespace (netns), the driver should set this feature flag to prevent +the port netdev from being moved out of the default netns. A netns-aware +driver/device would not set this flag and be responsible for partitioning +hardware to preserve netns containment. This means hardware cannot forward +traffic from a port in one namespace to another port in another namespace. + +Port Topology +^^^^^^^^^^^^^ + +The port netdevs representing the physical switch ports can be organized into +higher-level switching constructs. The default construct is a standalone +router port, used to offload L3 forwarding. Two or more ports can be bonded +together to form a LAG. Two or more ports (or LAGs) can be bridged to bridge +L2 networks. VLANs can be applied to sub-divide L2 networks. L2-over-L3 +tunnels can be built on ports. These constructs are built using standard Linux +tools such as the bridge driver, the bonding/team drivers, and netlink-based +tools such as iproute2. + +The switchdev driver can know a particular port's position in the topology by +monitoring NETDEV_CHANGEUPPER notifications. For example, a port moved into a +bond will see it's upper master change. If that bond is moved into a bridge, +the bond's upper master will change. And so on. The driver will track such +movements to know what position a port is in in the overall topology by +registering for netdevice events and acting on NETDEV_CHANGEUPPER. + +L2 Forwarding Offload +--------------------- + +The idea is to offload the L2 data forwarding (switching) path from the kernel +to the switchdev device by mirroring bridge FDB entries down to the device. An +FDB entry is the {port, MAC, VLAN} tuple forwarding destination. + +To offloading L2 bridging, the switchdev driver/device should support: + + - Static FDB entries installed on a bridge port + - Notification of learned/forgotten src mac/vlans from device + - STP state changes on the port + - VLAN flooding of multicast/broadcast and unknown unicast packets + +Static FDB Entries +^^^^^^^^^^^^^^^^^^ + +The switchdev driver should implement ndo_fdb_add, ndo_fdb_del and ndo_fdb_dump +to support static FDB entries installed to the device. Static bridge FDB +entries are installed, for example, using iproute2 bridge cmd: + + bridge fdb add ADDR dev DEV [vlan VID] [self] + +The driver should use the helper switchdev_port_fdb_xxx ops for ndo_fdb_xxx +ops, and handle add/delete/dump of SWITCHDEV_OBJ_PORT_FDB object using +switchdev_port_obj_xxx ops. + +XXX: what should be done if offloading this rule to hardware fails (for +example, due to full capacity in hardware tables) ? + +Note: by default, the bridge does not filter on VLAN and only bridges untagged +traffic. To enable VLAN support, turn on VLAN filtering: + + echo 1 >/sys/class/net/<bridge>/bridge/vlan_filtering + +Notification of Learned/Forgotten Source MAC/VLANs +^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ + +The switch device will learn/forget source MAC address/VLAN on ingress packets +and notify the switch driver of the mac/vlan/port tuples. The switch driver, +in turn, will notify the bridge driver using the switchdev notifier call: + + err = call_switchdev_notifiers(val, dev, info); + +Where val is SWITCHDEV_FDB_ADD when learning and SWITCHDEV_FDB_DEL when +forgetting, and info points to a struct switchdev_notifier_fdb_info. On +SWITCHDEV_FDB_ADD, the bridge driver will install the FDB entry into the +bridge's FDB and mark the entry as NTF_EXT_LEARNED. The iproute2 bridge +command will label these entries "offload": + + $ bridge fdb + 52:54:00:12:35:01 dev sw1p1 master br0 permanent + 00:02:00:00:02:00 dev sw1p1 master br0 offload + 00:02:00:00:02:00 dev sw1p1 self + 52:54:00:12:35:02 dev sw1p2 master br0 permanent + 00:02:00:00:03:00 dev sw1p2 master br0 offload + 00:02:00:00:03:00 dev sw1p2 self + 33:33:00:00:00:01 dev eth0 self permanent + 01:00:5e:00:00:01 dev eth0 self permanent + 33:33:ff:00:00:00 dev eth0 self permanent + 01:80:c2:00:00:0e dev eth0 self permanent + 33:33:00:00:00:01 dev br0 self permanent + 01:00:5e:00:00:01 dev br0 self permanent + 33:33:ff:12:35:01 dev br0 self permanent + +Learning on the port should be disabled on the bridge using the bridge command: + + bridge link set dev DEV learning off + +Learning on the device port should be enabled, as well as learning_sync: + + bridge link set dev DEV learning on self + bridge link set dev DEV learning_sync on self + +Learning_sync attribute enables syncing of the learned/forgotton FDB entry to +the bridge's FDB. It's possible, but not optimal, to enable learning on the +device port and on the bridge port, and disable learning_sync. + +To support learning and learning_sync port attributes, the driver implements +switchdev op switchdev_port_attr_get/set for SWITCHDEV_ATTR_PORT_BRIDGE_FLAGS. +The driver should initialize the attributes to the hardware defaults. + +FDB Ageing +^^^^^^^^^^ + +There are two FDB ageing models supported: 1) ageing by the device, and 2) +ageing by the kernel. Ageing by the device is preferred if many FDB entries +are supported. The driver calls call_switchdev_notifiers(SWITCHDEV_FDB_DEL, +...) to age out the FDB entry. In this model, ageing by the kernel should be +turned off. XXX: how to turn off ageing in kernel on a per-port basis or +otherwise prevent the kernel from ageing out the FDB entry? + +In the kernel ageing model, the standard bridge ageing mechanism is used to age +out stale FDB entries. To keep an FDB entry "alive", the driver should refresh +the FDB entry by calling call_switchdev_notifiers(SWITCHDEV_FDB_ADD, ...). The +notification will reset the FDB entry's last-used time to now. The driver +should rate limit refresh notifications, for example, no more than once a +second. If the FDB entry expires, ndo_fdb_del is called to remove entry from +the device. XXX: this last part isn't currently correct: ndo_fdb_del isn't +called, so the stale entry remains in device...this need to get fixed. + +FDB Flush +^^^^^^^^^ + +XXX: Unimplemented. Need to support FDB flush by bridge driver for port and +remove both static and learned FDB entries. + +STP State Change on Port +^^^^^^^^^^^^^^^^^^^^^^^^ + +Internally or with a third-party STP protocol implementation (e.g. mstpd), the +bridge driver maintains the STP state for ports, and will notify the switch +driver of STP state change on a port using the switchdev op +switchdev_attr_port_set for SWITCHDEV_ATTR_PORT_STP_UPDATE. + +State is one of BR_STATE_*. The switch driver can use STP state updates to +update ingress packet filter list for the port. For example, if port is +DISABLED, no packets should pass, but if port moves to BLOCKED, then STP BPDUs +and other IEEE 01:80:c2:xx:xx:xx link-local multicast packets can pass. + +Note that STP BDPUs are untagged and STP state applies to all VLANs on the port +so packet filters should be applied consistently across untagged and tagged +VLANs on the port. + +Flooding L2 domain +^^^^^^^^^^^^^^^^^^ + +For a given L2 VLAN domain, the switch device should flood multicast/broadcast +and unknown unicast packets to all ports in domain, if allowed by port's +current STP state. The switch driver, knowing which ports are within which +vlan L2 domain, can program the switch device for flooding. The packet should +also be sent to the port netdev for processing by the bridge driver. The +bridge should not reflood the packet to the same ports the device flooded. +XXX: the mechanism to avoid duplicate flood packets is being discuseed. + +It is possible for the switch device to not handle flooding and push the +packets up to the bridge driver for flooding. This is not ideal as the number +of ports scale in the L2 domain as the device is much more efficient at +flooding packets that software. + +IGMP Snooping +^^^^^^^^^^^^^ + +XXX: complete this section + + +L3 Routing Offload +------------------ + +Offloading L3 routing requires that device be programmed with FIB entries from +the kernel, with the device doing the FIB lookup and forwarding. The device +does a longest prefix match (LPM) on FIB entries matching route prefix and +forwards the packet to the matching FIB entry's nexthop(s) egress ports. + +To program the device, the driver implements support for +SWITCHDEV_OBJ_IPV[4|6]_FIB object using switchdev_port_obj_xxx ops. +switchdev_port_obj_add is used for both adding a new FIB entry to the device, +or modifying an existing entry on the device. + +XXX: Currently, only SWITCHDEV_OBJ_IPV4_FIB objects are supported. + +SWITCHDEV_OBJ_IPV4_FIB object passes: + + struct switchdev_obj_ipv4_fib { /* IPV4_FIB */ + u32 dst; + int dst_len; + struct fib_info *fi; + u8 tos; + u8 type; + u32 nlflags; + u32 tb_id; + } ipv4_fib; + +to add/modify/delete IPv4 dst/dest_len prefix on table tb_id. The *fi +structure holds details on the route and route's nexthops. *dev is one of the +port netdevs mentioned in the routes next hop list.

Neighbor mac +address discovery comes via the ARP (or ND) process and is available via the +arp_tbl neighbor table.
