The memory region where adjacency entries (nexthops) are stored is called the KVD linear and is configured during initialization with a size of 64K. Extend this area with 32K more entries, that will be partitioned into 64 groups of 0.5K entries, thereby allowing us to support weighted nexthops with high accuracy. Change the ratio between both types of hash entries, so as to prevent reduction in the number of double hash entries, which are used for IPv6 neighbours and routes with a prefix length greater than 64. Note that the user will be able to control all these sizes once the devlink resource manager is introduced.

The KVD linear (KVDL) allocator currently consists of a very large bitmap that reflects the KVDL's usage. The boundaries of each partition as well as their allocation size are represented using defines. This representation requires us to patch all the functions that act on a partition whenever the partitioning scheme is changed. In addition, it does not enable the dynamic configuration of the KVDL using the up-coming resource manager. Add objects to represent these partitions as well as the accompanying code that acts on them to perform allocations and de-allocations. In the following patches, this will allow us to easily add another partition as well as new operations to act on these partitions.

IPIP entries are created as soon as an offloadable device is created. That means that when such a device is later moved to a different VRF, the loopback device that backs the tunnel is wrong. Thus when an offloadable encapsulating netdevice moves from one VRF to another, make sure that the loopback is updated as necessary.

Current code for offloading IP-in-IP tunneling assumes that there is no decap without encap. But that's never true for IPv6 overlays, and is not true for IPv4 ones either, if net.ipv4.conf.*.rp_filter is unset. To support decap-only tunnels, an IPIP entry is now created as soon as an offloadable tunneling device is created. When that netdevice is up'd, a decap route is looked up and possibly offloaded. Thus decap is not handled implicitly as part of mlxsw_sp_ipip_entry_get() call anymore, but needs to be done explicitly after the get, if desired.

So far, all netdevice notifications that the driver cared about were related to its own ports, and mlxsw_sp could be retrieved from the netdevice's private data. For IP-in-IP offloading however, the driver cares about events on foreign netdevices, and getting at mlxsw_sp or router data structures from the handler is inconvenient. Therefore move the netdevice notifier blocks from global scope to struct mlxsw_sp to allow retrieval from the notifier block pointer itself.

When a multicast route is configured with trap-and-forward action, the packets should be marked with skb->offload_mr_fwd_mark, in order to prevent the packets from being forwarded again by the kernel ipmr module. Due to this, it is not possible to use the already existing multicast trap (MLXSW_TRAP_ID_ACL1) as the packet should be marked differently. Add the MLXSW_TRAP_ID_ACL2 which is for trap-and-forward multicast routes, and set the offload_mr_fwd_mark skb field in its handler.

Add three new traps needed for multicast routing: - PIM: Trap for PIM protocol control packets. - RPF: Trap for packets that fail the RPF check on a specific hardware route entry. - MULTICAST: Generic trap for multicast. It is used for routes that trap the packets to the CPU. The RPF and MULTICAST traps have rate limiters as these traps may have line-rate of packets trapped. The PIM trap has a rate limiter similarly to other L3 control protocols. The rate limiters are implemented by adding three new trap groups for the newly introduced traps.

When removing the offloading of mirred actions under matchall classifiers, mlxsw would find the destination port associated with the offloaded action and utilize it for undoing the configuration. Depending on the order by which ports are removed, it's possible that the destination port would get removed before the source port. In such a scenario, when actions would be flushed for the source port mlxsw would perform an illegal dereference as the destination port is no longer listed. Since the only item necessary for undoing the configuration on the destination side is the port-id and that in turn is already maintained by mlxsw on the source-port, simply stop trying to access the destination port and use the port-id directly instead.

The mlxsw driver relies on NETDEV_CHANGEUPPER events to configure the device in case a port is enslaved to a master netdev such as bridge or bond. Since the driver ignores events unrelated to its ports and their uppers, it's possible to engineer situations in which the device's data path differs from the kernel's. One example to such a situation is when a port is enslaved to a bond that is already enslaved to a bridge. When the bond was enslaved the driver ignored the event - as the bond wasn't one of its uppers - and therefore a bridge port instance isn't created in the device. Until such configurations are supported forbid them by checking that the upper device doesn't have uppers of its own.
