net/mlx5: Fix post parse infra to only parse every action once Caller of mlx5e_tc_act_post_parse() needs it to parse only the subset of actions starting after previous split and ending at the current action. However, that range is not provided as arguments and mlx5e_tc_act_post_parse() uses generic flow_action_for_each() that iterates over all flow actions. Not only this is redundant, it also causes a bug when mlx5e_tc_act->post_parse() callback is not idempotent since it will be called for every split. For example, ct action tc_act_post_parse_ct() callback obtains a reference to mlx5_ct_ft instance and calling it several times during parsing stage will cause reference counter imbalance. Fix the issue by providing a proper action range of the current split subset to mlx5e_tc_act_post_parse() and only calling mlx5e_tc_act->post_parse() for actions inside the subset range.

net/mlx5e: TC, Remove CT action reordering CT action reordering was done as a workaround when CT misses used to restore the relevant filter's tc chain and continuing sw processing from that chain. As such, there was a need to reorder CT action to be before any packet modifying actions (e.g mac rewrite). Currently (after patch "net/mlx5e: TC, Set CT miss to the specific ct action instance"), CT misses continues from the relevant ct action in software, and so reordering isn't needed anymore. Remove the reordering. Signed-off-by: Paul Blakey <paulb@nvidia.com> Reviewed-by: Roi Dayan <roid@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

net/mlx5e: TC, Support offloading police action Add parsing support by implementing struct mlx5e_tc_act for police action. TC rule with police actions is broken down into several rules in different tables. One rule with the original match in the original flow table, which set fte_id, do metering, and jump to the post_meter table. If there are more police actions, more rules are created for each of them. Besides, a last rule is created in the end. In post_meter table, there are two pre-defined rules, one is to drop packet if its packet color is RED, the other is to jump back to post_act table. As fte_id is updated before jumping, the rule for next meter is matched to do another round of metering (if there are multiple meters in the flow rule). Otherwise, last fte_id is matched and do the original actions.

net/mlx5e: Avoid checking offload capability in post_parse action During TC action parsing, the can_offload callback is called before calling the action's main parsing callback. Later on, the can_offload callback is called again before handling the action's post_parse callback if exists. Since the main parsing callback might have changed and set parsing params for the rule, following can_offload checks might fail because some parsing params were already set. Specifically, the ct action main parsing sets the ct param in the parsing status structure and when the second can_offload for ct action is called, before handling the ct post parsing, it will return an error since it checks this ct param to indicate multiple ct actions which are not supported. Therefore, the can_offload call is removed from the post parsing handling to prevent such cases. This is allowed since the first can_offload call will ensure that the action can be offloaded and the fact the code reached the post parsing handling already means that the action can be offloaded.

net/mlx5e: MPLSoUDP encap, support action vlan pop_eth explicitly Currently the MPLSoUDP encap offload does the L2 pop implicitly while adding such action explicitly (vlan eth_push) will cause the rule to not be offloaded. Solve it by adding offload support for vlan eth_push in case of MPLSoUDP decap case. Flow example: filter root protocol ip pref 1 flower chain 0 filter root protocol ip pref 1 flower chain 0 handle 0x1 eth_type ipv4 dst_ip 2.2.2.22 src_ip 2.2.2.21 in_hw in_hw_count 1 action order 1: vlan pop_eth pipe index 1 ref 1 bind 1 used_hw_stats delayed action order 2: mpls push protocol mpls_uc label 555 tc 3 ttl 255 pipe index 1 ref 1 bind 1 used_hw_stats delayed action order 3: tunnel_key set src_ip 8.8.8.21 dst_ip 8.8.8.22 dst_port 6635 csum tos 0x4 ttl 6 pipe index 1 ref 1 bind 1 used_hw_stats delayed action order 4: mirred (Egress Redirect to device bareudp0) stolen index 1 ref 1 bind 1 used_hw_stats delayed Signed-off-by: Maor Dickman <maord@nvidia.com> Reviewed-by: Roi Dayan <roid@nvidia.com> Signed-off-by: Jakub Kicinski <kuba@kernel.org>

net/mlx5e: MPLSoUDP decap, use vlan push_eth instead of pedit Currently action pedit of source and destination MACs is used to fill the MACs in L2 push step in MPLSoUDP decap offload, this isn't aligned to tc SW which use vlan eth_push action to do this.

net/mlx5e: Create new flow attr for multi table actions Some TC actions use post actions for their implementation. For example CT and sample actions. Create a new flow attr after each multi table action and create a post action rule for it. First flow attr being offloaded normally and linked to the next attr (post action rule) with setting an id on reg_c. Post action rules match the id on reg_c and continue to the next one. The flow counter is allocated on the last rule. Signed-off-by: Roi Dayan <roid@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>

net/mlx5e: Add tc action infrastructure Add an infrastructure to help parsing tc actions in a generic way. Supporting an action parser means implementing struct mlx5e_tc_act for that action. The infrastructure will give the possibility to be generic when parsing tc actions, i.e. parse_tc_nic_actions() and parse_tc_fdb_actions(). To parse tc actions a user needs to allocate a parse_state instance and pass it when iterating over the tc actions parsers. If a parser doesn't exists then a user can treat it as unsupported. To add an action parser a user needs to implement two callbacks. The can_offload() callback to quickly check if an action can be offloaded. The parse_action() callback to do actual parsing and prepare for offload. Add implementation for drop, trap, mark and accept action parsers with this commit to act as examples and implement usage of the new infrastructure for those actions.
