Currently, when a Subport RIF is configured, the LAG status and VLAN of the underlying port are read from the port itself. This is problematic, as we would like to have common code to configure all types of RIFs, which aren't necessarily bound to a port. Instead, embed the RIF in a struct specific to the Subport type, which contains all the necessary information. Signed-off-by:

In the following patches the RIF's configuration function is going to expect a RIF struct with all the necessary information. Therefore, allocate the RIF just before it's configured to the device. Signed-off-by:

The following patches are going to re-arrange the FID and RIF code, so that when the RIF is configured to the device based on the information present in the RIF struct (which points to a FID). For this reason, move the FID allocation to just before the RIF configuration. Signed-off-by:

As explained in the cover letter, since the introduction of the bridge offload in the mlxsw driver, information related to the offloaded bridge and bridge ports was stored in the individual port struct, mlxsw_sp_port. This lead to a bloated struct storing both physical properties of the port (e.g., autoneg status) as well as logical properties of an upper bridge port (e.g., learning, mrouter indication). While this might work well for simple devices, it proved to be hard to extend when stacked devices were taken into account and more advanced use-cases (e.g., IGMP snooping) considered. This patch removes the excess information from the above struct and instead stores it in more appropriate structs that represent the bridge port, the bridge itself and a VLAN configured on the bridge port. The membership of a port in a bridge is denoted using the Port-VLAN struct, which points to the bridge port and also member in the bridge VLAN group of the VLAN it represents. This allows us to completely remove the vPort abstraction and consolidate many of the code paths relating to VLAN-aware and unaware bridges. Note that the FID / vFID code is currently duplicated, but this will soon go away when the common FID core will be introduced. Signed-off-by:

Up until now we used to create FIDs upon the creation of VLAN uppers on top of the VLAN-aware bridge. This was done so that in case a router interface (RIF) was configured on top of the bridge, the FID would already be there. Instead, simplify the code and only create the FID upon RIF creation. This is an intermediary step towards the introduction of the common FID core, in which this code would be completely removed. Signed-off-by:

Currently, when port netdevs (or their uppers) are enslaved to a bridge, we simply propagate the CHANGEUPPER event all the way down and lose the context of the actual netdevice used as the bridge port. This leads to a lot of information hanging off the ports (and vPorts), which doesn't logically belong there, such as mrouter indication and unknown unicast flood state. Following patches are going to put the mlxsw_sp_port struct on diet and instead introduce a bridge port struct, where the above mentioned information belongs. But in order to do that, we need to be able to determine the bridge port netdevice, so propagate it down. Signed-off-by:

We're going to get rid of vPorts completely later in the patchset, but the router code is self-contained, so it's a good candidate to start the transition with. Convert all the functions that expects to operate on a vPort to operate on a Port-VLAN instead. Signed-off-by:

When a vPort is destroyed, it leaves the FID it's currently mapped to (if any) and drops the reference. The FID's leave function expects to get the vPort as its argument, but this will have to change when the vPort model is retired. Change the function signature to expect a Port-VLAN struct instead and patch the call sites accordingly. The code introduced in this patch will be removed later in the patchset, but this intermediary step is required in order to ease the code review. Signed-off-by:

This is the first step in the transition from the vPort model to a unified Port-VLAN structure. The new structure is defined and created / destroyed upon invocation of the 8021q ndos, but it's not actually used throughout the code. Subsequent patches will initialize it correctly and also create / destroy it upon switchdev's VLAN object. Signed-off-by:

We currently transition the port to "Virtual mode" upon the creation of its first VLAN upper, as we need to classify incoming packets to a FID using {Port, VID} and not only the VID. However, it's more appropriate to transition the port to this mode when the {Port, VID} are actually mapped to a FID. Either during the enslavement of the VLAN upper to a VLAN-unaware bridge or the configuration of a router port. Do this change now in preparation for the introduction of the FID core, where this operation will be encapsulated. To prevent regressions, this patch also explicitly configures an OVS slave to "Virtual mode". Otherwise, a packet that didn't hit an ACL rule could be classified to an existing FID based on a global VID-to-FID mapping, thus not incurring a FID mis-classification, which would otherwise trap the packet to the CPU to be processed by the OVS daemon.

During enslavement to a bridge, after the CHANGEUPPER is sent, the multicast enabled state of the bridge isn't propagated down to the offloading driver unless it's changed. This patch allows such drivers to query the multicast enabled state from the bridge, so that they'll be able to correctly configure their flood tables during port enslavement. In case multicast is disabled, unregistered multicast packets can be treated as broadcast and be flooded through all the bridge ports. Signed-off-by:

It's useful for drivers supporting bridge offload to be able to query the bridge's VLAN filtering state. Currently, upon enslavement to a bridge master, the offloading driver will only learn about the bridge's VLAN filtering state after the bridge device was already linked with its slave. Being able to query the bridge's VLAN filtering state allows such drivers to forbid enslavement in case resource couldn't be allocated for a VLAN-aware bridge and also choose the correct initialization routine for the enslaved port, which is dependent on the bridge type.

Andrew Lunn says: ==================== net: dsa: mv88e6xxx: Add basic SERDES support Some of the Marvell switches are SERDES interface, which must be powered up before packets can be passed.

Implement the port enable/disable callbacks, which enable/disable the SERDES interfaces, if applicable. This should save a bit of power/heat. We also need to enable SERDES on CPU and DSA ports, so keep the existing call to the op, but make it conditional. Signed-off-by:

The mv88e6390X family has 8 SERDES lanes. These can be used for 2 10Gbps ports, ports 9 or 10. If these ports are used at slower speeds, the SERDES lanes become available for other ports for 1000Base-X. Signed-off-by:

lio_enable_irq (called by napi poll) is reporting to Octeon an inaccurate count of processed rx packets causing Octeon to eventually stop forwarding packets to the host. Fix it by using this formula for an accurate count: processed rx packets = droq->pkt_count - droq->pkts_pending Also increase SOFT_COMMAND_BUFFER_SIZE to match what the firmware expects.

There's a rare pci_driver.probe failure of the VF driver that's caused by PF/VF handshake going out of sync. The culprit is octeon_mbox_write() who ignores an ack timeout condition; it just keeps unconditionally writing all elements of mbox_cmd->data[] even when the other side is not ready for them. Fix it by making each write of mbox_cmd->data[i] conditional to having previously received an ack. Also fix the octeon_mbox_state enum such that each state gets a unique value. Also add ULL suffix to numeric literals in macro definitions. Signed-off-by:

There is currently no way for a program scanning /sys to know whether a network device is attached to a particular PHY device, just like the PHY device is not pointed back to its attached network device. Create a symbolic link in the network device's namespace named "phydev" which points to the PHY device and create a symbolic link in the PHY device's namespace named "attached_dev" that points back to the network device. These links are set up during phy_attach_direct() and removed during phy_detach() for symetry. Signed-off-by:

Convert inet_rtm_getroute to use ip_route_input_rcu and ip_route_output_key_hash_rcu passing the fib_result arg to both. The rcu lock is held through the creation of the response, so the rtable/dst does not need to be attached to the skb and is passed to rt_fill_info directly. In converting from ip_route_output_key to ip_route_output_key_hash_rcu the xfrm_lookup_route in ip_route_output_flow is dropped since flowi4_proto is not set for a route get request. Signed-off-by:
