L2 upper device needs to propagate neigh_construct/destroy calls down to lower devices. Do this by defining default ndo functions and use them in team, bond, bridge and vlan. Signed-off-by:

Saeed Mahameed says: ==================== Mellanox 100G mlx5 ethtool ntuple steering This series adds Ethernet ethtool ntuple steering 'ethtool -N|U' and exposes two more counter sets to Ethtool statistics, RDMA vport and global flow control statistics. We start from three refactoring patches of the flow steering infrastructure - mlx5_add_flow_rule will now receive mlx5 flow spec to simplify and reduce number of parameters - All low level steering objects are now wrapped in mlx5_flow_steering structure for better encapsulation - Flow steering object will now be removed properly and generically rather than traversing on a well-known steering tree objects Patch#4 adds the infrastructure and the data structures needed for the ethtool ntuple steering, all implemented in a new file 'en_fs_ethtool.c'. Add the support for set_rxnfc ethtool callback to add/remove/replace a flow spec of ethter type L2. Patch#5 adds the support for L3/L4 flow specs and a higher priority in favor for L3/L4 rules when interleaving with L2 rules. Patch#6 adds the support for get_rxnfc ethtool callback. Patch#7,8 adds RDMA vport and global flow control statistics. Applied on top: 8186f6e3 ('net-next: mediatek: fix compile error inside mtk_poll_controller()') ==================== Signed-off-by: -

Add support to add flow steering rules with ethtool of L3/L4 flow types (ip4/tcp4/udp4). Those rules will be in higher priority than l2 flow rules, in order to prefer more specific rules. Mask is not supported for l3/l4 flow types. Signed-off-by:

Commit 80673029 ("net-next: mediatek: add support for IRQ grouping") adds handling for irq 1 and 2 to the uninit function but did not remove irq 0 which is not used since irq grouping was introduced. Fix this by removing the superfluous call to free_irq(). Reported-by:

Jiri Pirko says: ==================== mlxsw: Implement basic FIB offload and router interfaces Introduce LPM trees management including virtual router management for HW. Implement basic FIB offloading using switchdev FIB objects. For now only support local routes and direct routes (next-hop support will be introduced in a follow-up patchset). Introduce router interfaces in patches 10-14. ==================== Signed-off-by: -

As with the previously introduced L3 interfaces, listen to 'inetaddr' notifications sent for bridges devices configured on top of the port netdevs and create / destroy router interfaces (RIFs) accordingly. This also includes VLAN devices configured on top of the VLAN-aware bridge. The RIFs will be destroyed either when the last IP address is removed or when the underlying FID is is destroyed. Signed-off-by:

Ido Schimmel authored
Before introducing support for L3 interfaces on top of the VLAN-aware bridge we need to add some missing infrastructure. Such an interface can either be the bridge device itself or a VLAN device on top of it. In the first case the router interface (RIF) is associated with FID 1, which is created whenever the first port netdev joins the bridge. We currently assume the default PVID is 1 and that it's already created, as it seems reasonable. This can be extended in the future. However, in the second case it's entirely possible we've yet to create a matching FID. This can happen if the VLAN device was configured before making any bridge port member in the VLAN. Prevent such ordering problems by using the VLAN device's CHANGEUPPER event to configure the FID. Make the VLAN device hold a reference to the FID and prevent it from being destroyed even if none of the port netdevs is using it. Signed-off-by:

Previous commit deprecated the vFIDs used to get traffic to the CPU ('port_vfids'). Thus, we now use the vFIDs as god intended and the artificial split is no longer needed. Rename functions and variables to reflect that. Signed-off-by: -
Ido Schimmel authored
Up until now we only supported bridged interfaces. Packets ingressing through the switch ports were either classified to FIDs (in the case of the VLAN-aware bridge) or vFIDs (in the case of VLAN-unaware bridges). The packets were then forwarded according to the FDB. Routing was done entirely in slowpath, by splitting the vFID range in two and using the lower 0.5K vFIDs as dummy bridges that simply flooded all incoming traffic to the CPU. Instead, allow packets to be routed in the device by creating router interfaces (RIFs) that will direct them to the router block. Specifically, the RIFs introduced here are Sub-port RIFs used for VLAN devices and port netdevs. Packets ingressing from the {Port / LAG ID, VID} with which the RIF was programmed with will be assigned to a special kind of FIDs called rFIDs and from there directed to the router. Create a RIF whenever the first IPv4 address was programmed on a VLAN / LAG / port netdev. Destroy it upon removal of the last IPv4 address. Receive these notifications by registering for the 'inetaddr' notification chain. A non-zero (10) priority is used for the notification block, so that RIFs will be created before routes are offloaded via FIB code. Note that another trigger for RIF destruction are CHANGEUPPER notifications causing the underlying FID's reference count to go down to zero. This can happen, for example, when a VLAN netdev with an IP address is put under bridge. While this configuration doesn't make sense it does cause the device and the kernel to get out of sync when the netdev is unbridged. We intend to address this in the future, hopefully in current cycle. Finally, Remove the lower 0.5K vFIDs, as they are deprecated by the RIFs, which will trap packets according to their DIP.

We are just about to introduce router interfaces (RIFs), but before that we need to be able update the device with the correct RIF attributes whenever they change for the netdev the RIF is backing. Two such attributes are MTU and MAC. The MAC is used both to set the source MAC of packets egressing from the RIF and also to program an FDB rule that will direct packets to the router block. Use the existing netdevice notification block and respond to CHANGEADDR and CHANGEMTU accordingly. Store both attributes in the RIF struct in case we need to revert to old attributes following a failed update. Signed-off-by:

Virtual router is a construct used inside HW. In this implementation we map kernel tables to virtual routers one to one. Introduce management logic to create virtual routers when needed and destroy in case they are no longer in use. According to that, call into LPM tree management. Each virtual router is always bound to one LPM tree. Signed-off-by:

Introduce basic LPM tree management allowing to share the trees in between tables if the used prefixes in the tables are the same. Build the tree structure according to the used prefixes. Although it is not optimal for many use cases, this initial implementation does only simple linear left-tree. More advanced structures will be introduced later on, possibly including mechanisms to change trees on the fly. Signed-off-by:
