The pre-tunnel action includes the destination IP address and is used to calculate the next hop from from the neighbour table. Much of the IPv4 tunnel actions can be reused for IPv6 tunnels. Change the names of associated functions and structs to remove the IPv4 identifier and make minor modifcations to support IPv6 tunnel actions.

nfp: flower: detect potential pre-tunnel rules Pre-tunnel rules are used when the tunnel end-point is on an 'internal port'. These rules are used to direct the tunnelled packets (based on outer header fields) to the internal port where they can be detunnelled. The rule must send the packet to ingress the internal port at the TC layer. Currently FW does not support an action to send to ingress so cannot offload such rules. However, in preparation for populating the pre-tunnel table to represent such rules, check for rules that send to the ingress of an internal port and mark them as such. Further validation of such rules is left to subsequent patches.

To avoid a follow up patch that would edit the same LoCs in the drivers, this patch also wraps this new flow match structure around the flow rule object. This new structure will also contain the flow actions in follow up patches. This introduces two new interfaces: bool flow_rule_match_key(rule, dissector_id) that returns true if a given matching key is set on, and: flow_rule_match_XYZ(rule, &match); To fetch the matching side XYZ into the match container structure, to retrieve the key and the mask with one single call.

nfp: flower: offload tos and tunnel flags for ipv4 udp tunnels Extract the tos and the tunnel flags from the tunnel key and offload these action fields. Only the checksum and tunnel key flags are implemented in fw so reject offloads of other flags. The tunnel key flag is always considered set in the fw so enforce that it is set in the rule. Note that the compulsory setting of the tunnel key flag and optional setting of checksum is inline with how tc currently generates ipv4 udp tunnel actions.

nfp: flower: compute link aggregation action If the egress device of an offloaded rule is a LAG port, then encode the output port to the NFP with a LAG identifier and the offloaded group ID. A prelag action is also offloaded which must be the first action of the series (although may appear after other pre-actions - e.g. tunnels). This causes the FW to check that it has the necessary information to output to the requested LAG port. If it does not, the packet is sent to the kernel before any other actions are applied to it.

nfp: flower: set tunnel ttl value to net default Firmware requires that the ttl value for an encapsulating ipv4 tunnel header be included as an action field. Prior to the support of Geneve tunnel encap (when ttl set was removed completely), ttl value was extracted from the tunnel key. However, tests have shown that this can still produce a ttl of 0. Fix the issue by setting the namespace default value for each new tunnel. Follow up patch for net-next will do a full route lookup.

act_mirred: get rid of tcfm_ifindex from struct tcf_mirred tcfm_dev always points to the correct netdev and we already hold a refcnt, so no need to use tcfm_ifindex to lookup again. If we would support moving target netdev across netns, using pointer would be better than ifindex. This also fixes dumping obsolete ifindex, now after the target device is gone we just dump 0 as ifindex.

nfp: refuse offloading filters that redirects to upper devices Previously we did not ensure that a netdev is a representative netdev before dereferencing its private data. This can occur when an upper netdev is created on a representative netdev. This patch corrects this by first ensuring that the netdev is a representative netdev before using it. Checking only switchdev_port_same_parent_id is not sufficient to ensure that we can safely use the netdev. Failing to check that the netdev is also a representative netdev would result in incorrect dereferencing.
