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

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

v7: rebase on top of net-next. Dropping previous Acked-by tags since
this one is slightly large, and it would be good another look after
this rebase.

This patch wraps the dissector key and mask - that flower uses to
represent the matching side - around the flow_match structure.
To avoid a follow up patch that would edit the same LoCs in the drivers,
this patch also wraps this new flow match structure around the flow rule
object. This new structure will also contain the flow actions in follow
up patches.
This introduces two new interfaces:
bool flow_rule_match_key(rule, dissector_id)
that returns true if a given matching key is set on, and:
flow_rule_match_XYZ(rule, &match);
To fetch the matching side XYZ into the match container structure, to
retrieve the key and the mask with one single call.

v7: rebase on top of net-next. Dropping previous Acked-by tags since
this one is slightly large, and it would be good another look after
this rebase.

This patch adds pedit_headers_action structure to store the result of
parsing tc pedit actions. Then, it calls alloc_tc_pedit_action() to
populate the mlx5e hardware intermediate representation once all actions
have been parsed.
This patch comes in preparation for the new flow_action infrastructure,
where each packet mangling comes in an separated action, ie. not packed
as in tc pedit.

This patch provides the flow_stats structure that acts as container for
tc_cls_flower_offload, then we can use to restore the statistics on the
existing TC actions. Hence, tcf_exts_stats_update() is not used from
drivers anymore.

These actions need to be added to support the ethtool_rx_flow interface.
The queue action includes a field to specify the RSS context, that is
set via FLOW_RSS flow type flag and the rss_context field in struct
ethtool_rxnfc, plus the corresponding queue index. FLOW_RSS implies that
rss_context is non-zero, therefore, queue.ctx == 0 means that FLOW_RSS
was not set. Also add a field to store the vf index which is stored in
the ethtool_rxnfc ring_cookie field.

This is a preparation patch to reuse the existing TC flower codebase
from ethtool_rx_flow_spec.
This patch is merely moving the core ethtool_rx_flow_spec parser after
tc flower offload driver code so we can skip a few forward function
declarations in the follow up patch.

This is a preparation patch to reuse the existing TC flower codebase
from ethtool_rx_flow_spec.
This patch is merely moving the core ethtool_rx_flow_spec parser after
tc flower offload driver code so we can skip a few forward function
declarations in the follow up patch.

The qede driver supports for ethtool_rx_flow_spec and flower, both
codebases look very similar.
This patch uses the ethtool_rx_flow_rule() infrastructure to remove the
duplicated ethtool_rx_flow_spec parser and consolidate ACL offload
support around the flow_rule infrastructure.
Furthermore, more code can be consolidated by merging
qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions
also look very similar.
This driver currently provides simple ACL support, such as 5-tuple
matching, drop policy and queue to CPU.
Drivers that support more features can benefit from this infrastructure
to save even more redundant codebase.

The qede driver supports for ethtool_rx_flow_spec and flower, both
codebases look very similar.
This patch uses the ethtool_rx_flow_rule() infrastructure to remove the
duplicated ethtool_rx_flow_spec parser and consolidate ACL offload
support around the flow_rule infrastructure.
Furthermore, more code can be consolidated by merging
qede_add_cls_rule() and qede_add_tc_flower_fltr(), these two functions
also look very similar.
This driver currently provides simple ACL support, such as 5-tuple
matching, drop policy and queue to CPU.
Drivers that support more features can benefit from this infrastructure
to save even more redundant codebase.

Applied to net-next, let's see where this goes.
I'll push this out after my build testing completes.
Thanks!
