2020-01-25mlxsw: spectrum_qdisc: Extract a common leaf unoffload functionPetr Machata
When the RED Qdisc is unoffloaded, it needs to reduce the reported backlog by the amount that is in the HW, so that only the SW backlog is contained in the counter. The same thing will need to be done by TBF, and likely any other leaf Qdisc as well. Extract a helper mlxsw_sp_qdisc_leaf_unoffload() and call it from mlxsw_sp_qdisc_red_unoffload().

In order to support all of the supported stats that are available in legacy mode for switchdev uplink representors, convert rep stats infrastructure to reuse struct mlx5e_stats_grp that is already used when device is in legacy mode. Refactor rep code to use array of mlx5e_stats_grp structures (constructed using macros provided by stats infra) to fill/update stats, instead of fixed hardcoded set of values.

2020-01-22net/mlx5e: Add mlx5e_flower_parse_meta supportwenxu
In the flowtables offload all the devices in the flowtables share the same flow_block. An offload rule will be installed on all the devices. This scenario is not correct. It is no problem if there are only two devices in the flowtable, The rule with ingress and egress on the same device can be reject by driver. But more than two devices in the flowtable will install the wrong rules on hardware. For example: Three devices in a offload flowtables: dev_a, dev_b, dev_c A rule ingress from dev_a and egress to dev_b: The rule will install on device dev_a. The rule will try to install on dev_b but failed for ingress and egress on the same device. The rule will install on dev_c. This is not correct. The flowtables offload avoid this case through restricting the ingress dev with FLOW_DISSECTOR_KEY_META. So the mlx5e driver also should support the FLOW_DISSECTOR_KEY_META parse.
