[PATCH net-next,v4 00/12] add flow_rule infrastructure

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

Hi,

This patchset is another iteration to introduce an in-kernel intermediate
representation (IR) to express ACL hardware offloads [1] [2] [3].

Changes from previous version, based on feedback from:

* Marcelo Ricardo Leitner:
	- Fix bisect-ability due to update in flow_rule_alloc().
	- s/key/entry variable name for struct flow_action_entry in
	  tc_setup_flow_action().
	- Rename qede_parse_flower_attr() to qede_parse_flow_attr().
	  Remove _tc_ infix in qede parser too.

* Jiri Pirko:
	- Rename to ethtool_rx_flow_rule_create() and
	  ethtool_rx_flow_rule_destroy().

* Florian Fainelli:
	- Use BIT() ethtool_rx_flow_rule_create() to .used_keys.
	- Add support for FLOW_EXT and FLOW_MAC_EXT to
	  ethtool_rx_flow_rule_create().
	- ethtool inverts masks from userspace before passing the
	  ethtool_rx_flow_rule blob to the kernel.
	- Use post-increment in flow_action_for_each().

Other misc updates I made are:
	- Use "flow_offload:" tag in patch subject whenever possible.
	- Fix tos field in ethtool_rx_flow_rule_create().
	- Remove unused flow_rule_match_basic() from bcm_sf2.

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 basic 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
