2019-02-06flow_offload: add wake-up-on-lan and queue to flow_actionPablo Neira Ayuso1-0/+7
These actions need to be added to support the ethtool_rx_flow interface. The queue action includes a field to specify the RSS context, that is set via FLOW_RSS flow type flag and the rss_context field in struct ethtool_rxnfc, plus the corresponding queue index. FLOW_RSS implies that rss_context is non-zero, therefore, queue.ctx == 0 means that FLOW_RSS was not set. Also add a field to store the vf index which is stored in the ethtool_rxnfc ring_cookie field.

2019-02-06flow_offload: add statistics retrieval infrastructure and use itPablo Neira Ayuso1-0/+14
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 action infrastructurePablo Neira Ayuso1-1/+68
This new infrastructure defines the nic actions that you can perform from existing network drivers. This infrastructure allows us to avoid a direct dependency with the native software TC action representation.

2019-02-06flow_offload: add flow_rule and flow_match structures and use themPablo Neira Ayuso1-0/+115
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.
