When a netdev is configured with an IP address a router interface (RIF) should be configured for it in the device. Allow configuration of RIFs based on IPv6 address notifications as well as IPv4. Note that the RIF exists as long as an IP address is configured on the netdev, regardless of the address family.

In commit 1c6c6d22 ("mlxsw: spectrum: Mirror certain packets to CPU") we marked packets that were mirrored to the CPU, so that they won't be flooded again by the bridge driver. However, certain packets are trapped in the device's router block, after passing through the bridge block where they were potentially flooded. Mark all packets coming from L3 traps, so that they won't be potentially flooded again by the bridge driver.

Add callback to the ethtool flash_device op. This callback uses the mlxfw module to flash the new firmware file to the device. As the firmware flash process takes about 20 seconds and ethtool takes the rtnl lock during the flash_device callback, release the rtnl lock at the beginning of the flash process and take it again before leaving the callback. This way, the rtnl is not held during the process. To make sure the device does not get deleted during the flash process, take a reference to it before releasing the rtnl lock.

The device supports three types of FIDs. 802.1Q and 802.1D FIDs for VLAN-aware and VLAN-unaware bridges (respectively) and rFIDs to transport packets to the router block. The different users (e.g., bridge, router, ACLs) of the FIDs infrastructure need not know about the internal FIDs implementation and can therefore interact with it using a restricted set of exported functions. By encapsulating the entire FID logic and hiding it from the rest of the driver we get a code base that it much simpler and easier to work with and extend. For example, in the current Spectrum ASIC only 802.1D FIDs can be assigned a VNI, but future ASICs will also support 802.1Q FIDs. With this patch in place, support for future ASICs can be easily added by implementing a new FID operations according to their capabilities.

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.

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.

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.

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.

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.

In virtual mode, packets are classified to FIDs based on their ingress port and VLAN whereas in non-virtual mode only the VLAN is taken into account. Currently ports are initialized to use virtual mode due to the presence of the PVID vPort. However, we're going to transition ports between both modes based on the FIDs they use and not merely based on the presence on a VLAN upper. Therefore, during initialization, no mode will be explicitly set. Since the Programmer's Reference Manual (PRM) doesn't specify a default, explicitly set the port to non-virtual mode and later transition the port between both modes based on the FIDs it uses. In a follow-up patchset, this step will be moved to the common FID core where it logically belongs.

When a netdev is enslaved to a VRF master, its router interface (RIF) needs to be destroyed (if exists) and a new one created using the corresponding virtual router (VR). >From the driver's perspective, the above is equivalent to an inetaddr event sent for this netdev. Therefore, when a port netdev (or its uppers) are enslaved to a VRF master, call the same function that would've been called had a NETDEV_UP was sent for this netdev in the inetaddr notification chain. This patch also fixes a bug when a LAG netdev with an existing RIF is enslaved to a VRF. Before this patch, each LAG port would drop the reference on the RIF, but would re-join the same one (in the wrong VR) soon after. With this patch, the corresponding RIF is first destroyed and a new one is created using the correct VR.
