2019-02-12mlxsw: spectrum_flower: Fix VLAN modify action supportIdo Schimmel1-2/+1
The driver does not support VLAN push and pop, but only VLAN modify.

2019-02-06flow_offload: add statistics retrieval infrastructure and use itPablo Neira Ayuso1-1/+1
This patch provides the flow_stats structure that acts as container for tc_cls_flower_offload, then we can use to restore the statistics on the existing TC actions. Hence, tcf_exts_stats_update() is not used from drivers anymore. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org> Acked-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S.

2019-02-06flow_offload: add flow_rule and flow_match structures and use themPablo Neira Ayuso1-114/+88
This patch wraps the dissector key and mask - that flower uses to represent the matching side - around the flow_match structure. 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.

2018-12-11mlxsw: spectrum_acl: Support rule creation without action creationNir Dotan1-1/+1
Up until now, when ACL rule was created its action was created with it. It suits well for tc flower where ACL rule always needs an action, however it does not suit multicast router, where the action is created prior to setting a route, which in Spectrum-2 is actually an ACL rule. Add support for rule creation without action creation. Do it by adding afa_block argument to mlxsw_sp_acl_rule_create, which if NULL then an action would be created, also add an indication within struct mlxsw_sp_acl_rule_info that tells if the action should be destroyed when the rule is destroyed.

Since cld_flower provides information about the filter template for specific chain, use this information in order to prepare a region. Use the template to find out what elements are going to be used and pass that down to mlxsw_sp_acl_tcam_group_add(). Later on, when the first filter is inserted, the mlxsw_sp_acl_tcam_group_use_patterns() function would use this element usage information instead of looking up a pattern.

If we would support moving target netdev across netns, using pointer would be better than ifindex.

2017-05-26mlxsw: spectrum: Implement common FID coreIdo Schimmel1-1/+5
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.
