[PATCH net-next,v5 00/12] add flow_rule infrastructure

[Pablo Neira Ayuso <pablo@netfilter.org>]

Hi,

This is another iteration of the in-kernel intermediate representation
(IR) that allows to express ACL hardware offloads using one unified
representation from the driver side for the ethtool and the tc
frontends [1] [2] [3].

In words of Michal Kubecek:

"... the ethtool interface can apply four types of action to matching
packets:

  - put into a specific queue
  - discard
  - distribute accross the queues according to a RSS context
  - use the rule as a wake-on-lan filter"

This new round now supports for these four types, that can be mapped to
the flow_rule representation.

Changes from previous version:

* Michal Kubecek:
	- Add support for FLOW_RSS flag to the ethtool_rx_flow_spec
	  to flow_rule translator.

* Venkat Duvvuru:
	- Fix accidental swapping of flow_stats_update() bytes and
	  packets parameter.

* kbuild robot:
	- Fix double kfree in error path from cls_flower, via Julian Lawal.
	- Fix enum type mismatch in nfp driver reported by sparse
	  checks.

Please apply, thanks.

Pablo Neira Ayuso (12):
  flow_offload: add flow_rule and flow_match structures and use them
  net/mlx5e: support for two independent packet edit actions
  flow_offload: add flow action infrastructure
  cls_api: add translator to flow_action representation
  flow_offload: add statistics retrieval infrastructure and use it
  drivers: net: use flow action infrastructure
  cls_flower: don't expose TC actions to drivers anymore
  flow_offload: add wake-up-on-lan and queue to flow_action
  ethtool: add ethtool_rx_flow_spec to flow_rule structure translator
  dsa: bcm_sf2: use flow_rule infrastructure
  qede: place ethtool_rx_flow_spec after code after TC flower codebase
  qede: use ethtool_rx_flow_rule() to remove duplicated parser code
