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
