Add do_mark_test(), which is to do_ecn_test() like do_drop_test() is to do_red_test(): meant to test that actions on the RED mark qevent block are offloaded, and executed on ECN-marked packets. The test splits install_qdisc() into its constituents, install_root_qdisc() and install_qdisc_tcX(). This is in order to test that when mirroring is enabled on one TC, the other TC does not mirror.

The RED "mark" qevent can be offloaded under similar conditions as the RED "early_drop" qevent. Therefore recognize its binding type in the TC_SETUP_BLOCK handler and translate to the right SPAN trigger, with the right set of supported actions. Signed-off-by:

One block can be bound to several qevents. The qevent type that the block is bound to determines which actions make sense in a given context. In the particular case of mlxsw, trap cannot be offloaded on a RED mark qevent, because the trap contract specifies that the packet is dropped in the HW datapath, and the HW trigger that the action is offloaded to is always forwarding the packet (in addition to marking in). Therefore keep track of which actions are permissible at each binding block. When an attempt is made to bind a certain action at a binding point where it is not supported, bounce the request.

The following patches will configure the MLXSW_SP_SPAN_TRIGGER_ECN mirroring trigger. This trigger is considered "egress", unlike the previously-offloaded _EARLY_DROP. Add a helper to spectrum_span, mlxsw_sp_span_trigger_is_ingress(), to classify triggers to ingress and egress. Pass result of this instead of hardcoding true when calling mlxsw_sp_span_analyzed_port_get()/_put(). Signed-off-by:

Implement ndo_setup_tc net device callback for TC HW offload on PF device. ndo_setup_tc provides support for HW offloading various TC filters. Add support for configuring the following filter with tc-flower: - default L2 filters (src/dst mac addresses, ethertype, VLAN) - variations of L3, L3+L4, L2+L3+L4 filters using advanced filters (including ipv4 and ipv6 addresses). Allow for adding/removing TC flows when PF device is configured in eswitch switchdev mode. Two types of actions are supported at the moment: FLOW_ACTION_DROP and FLOW_ACTION_REDIRECT.

There is no way to change default lan_en and lb_en flags while adding new rule. Add function that allows changing these flags on rule determined by rule id and recipe id. Function checks if the rule is presented on regular rules list or advance rules list and call the appropriate function to update rule entry. As rules with ICE_SW_LKUP_DFLT recipe aren't tracked in a list, implement function which updates flags without searching for rules based only on rule id. Signed-off-by:

To remove advanced rule the same protocols list like in adding should be send to function. Based on this information list of advanced rules is searched to find the correct rule id. Remove advanced rule if it forwards to only one VSI. If it forwards to list of VSI remove only input VSI from this list. Introduce function to remove rule by id. It is used in case rule needs to be removed even if it forwards to the list of VSI. Allow removing all advanced rules from a particular VSI. It is useful in rebuilding VSI path. Co-developed-by:

Define dummy packet headers to allow adding advanced rules in HW. This header is used as admin queue command parameter for adding a rule. The firmware will extract correct fields and will use them in look ups. Define each supported packets header and offsets to words used in recipe. Supported headers: - MAC + IPv4 + UDP - MAC + VLAN + IPv4 + UDP - MAC + IPv4 + TCP - MAC + VLAN + IPv4 + TCP - MAC + IPv6 + UDP - MAC + VLAN + IPv6 + UDP - MAC + IPv6 + TCP - MAC + VLAN + IPv6 + TCP Add code for creating an advanced rule. Rule needs to match defined dummy packet, if not return error, which means that this type of rule isn't currently supported. The first step in adding advanced rule is searching for an advanced recipe matching this kind of rule. If it doesn't exist new recipe is created. Dummy packet has to be filled with the correct header field value from the rule definition. It will be used to do look up in HW. Support searching for existing advance rule entry. It is used in case of adding the same rule on different VSI. In this case, instead of creating new rule, the existing one should be updated with refreshed VSI list. Add initialization for prof_res_bm_init flag to zero so that the possible resource for fv in the files can be initialized. Co-developed-by:

These changes introduce code for creating advanced recipes for the switch in hardware. There are a couple of recipes already defined in the HW. They apply to matching on basic protocol headers, like MAC, VLAN, MACVLAN, ethertype or direction (promiscuous), etc.. If the user wants to match on other protocol headers (eg. ip address, src/dst port etc.) or different variation of already supported protocols, there is a need to create new, more complex recipe. That new recipe is referred as 'advanced recipe', and the filtering rule created on top of that recipe is called 'advanced rule'. One recipe can have up to 5 words, but the first word is always reserved for match on switch id, so the driver can define up to 4 words for one recipe. To support recipes with more words up to 5 recipes can be chained, so 20 words can be programmed for look up. Input for adding recipe function is a list of protocols to support. Based on this list correct profile is being chosen. Correct profile means that it contains all protocol types from a list. Each profile have up to 48 field vector words and each of this word have protocol id and offset. These two fields need to match with input data for adding recipe function. If the correct profile can't be found the function returns an error. The next step after finding the correct profile is grouping words into groups. One group can have up to 4 words. This is done to simplify sending recipes to HW (because recipe also can have up to 4 words). In case of chaining (so when look up consists of more than 4 words) last recipe will always have results from the previous recipes used as words. A recipe to profile map is used to store information about which profile is associate with this recipe. This map is an array of 64 elements (max number of recipes) and each element is a 256 bits bitmap (max number of profiles) Profile to recipe map is used to store information about which recipe is associate with this profile. This map is an array of 256 elements (max number of profiles) and each element is a 64 bits bitmap (max number of recipes) Signed-off-by:

Implement functions to manage profiles and field vectors in hardware. In hardware, there are up to 256 profiles and each of these profiles can have 48 field vector words. Each field vector word is described by protocol id and offset in the packet. To add a new recipe all used profiles need to be searched. If the profile contains all required protocol ids and offsets from the recipe it can be used. The driver has to add this profile to recipe association to tell hardware that newly added recipe is going to be associated with this profile. The amount of used profiles depend on the package. To avoid searching across not used profile, max profile id value is calculated at init flow. The profile is considered as unused when all field vector words in the profile are invalid (protocol id 0xff and offset 0x1ff). Profiles are read from the package section ICE_SID_FLD_VEC_SW. Empty field vector words can be used for recipe results. Store all unused field vector words in prof_res_bm. It is a 256 elements array (max number of profiles) each element is a 48 bit bitmap (max number of field vector words). For now, support only non-tunnel profiles type. Co-developed-by:

Add code to manage recipes and profiles on admin queue layer. Allow the driver to add a new recipe and update an existing one. Get a recipe and get a recipe to profile association is mostly used in update existing recipes code. Only default recipes can be updated. An update is done by reading recipes from HW, changing their params and calling add recipe command. Support following admin queue commands: - ice_aqc_opc_add_recipe (0x0290) - create a recipe with protocol header information and other details that determine how this recipe filter works - ice_aqc_opc_recipe_to_profile (0x0291) - associate a switch recipe to a profile - ice_aqc_opc_get_recipe (0x0292) - get details of an existing recipe - ice_aqc_opc_get_recipe_to_profile (0x0293) - get a recipe associated with profile ID Define ICE_AQC_RES_TYPE_RECIPE resource type to hold a switch recipe. It is needed when a new switch recipe needs to be created. Co-developed-by:

This patch separates the logic of configuring hardware maximum transmit frame size and receive frame size. This simplifies the logic to calculate receive buffer size and using cqe descriptor of different size. Also additional size of skb_shared_info structure is allocated for each receive buffer pointer given to hardware which is not necessary. Hence change the size calculation to remove the size of skb_shared_info. Add a check for array out of bounds while adding fragments to the network stack. Signed-off-by:
