Hi,
This patchset, as is, allows us to reuse the driver codebase to
configure ACL hardware offloads for the ethtool_rxnfc and the TC flower
interfaces. A few clients for this infrastructure are presented, such as
the bcm_sf2 and the qede drivers, for reference. Moreover all of the
existing drivers in the tree are converted to use this infrastructure.
This patchset is re-using the existing flow dissector infrastructure
that was introduced by Jiri Pirko et al. so the amount of abstractions
that this patchset adds are minimal. Well, just a few wrapper structures
for the selector side of the rules. And, in order to express actions,
this patchset exposes an action API that is based on the existing TC
action infrastructure and what existing drivers already support on that
front.
v7: This patchset is a rebase on top of the net-next tree, after
addressing questions and feedback from driver developers in the
last batch.
Please, apply. Thanks!
P.S: I would like to thank driver developers for their fruitful
cooperation and feedback, which has been very useful to shape
the layout of this incremental work on top of the existing
infrastructure. 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
