Subject: [PATCH v3 net-next 0/3] net/sched: act_police: add support for packet-per-second policing
Date: Fri, 12 Mar 2021 15:08:28 +0100 [thread overview]
Message-ID: <20210312140831.23346-1-simon.horman@netronome.com> (raw)
This series enhances the TC policer action implementation to allow a
policer action instance to enforce a rate-limit based on
packets-per-second, configurable using a packet-per-second rate and burst
parameters.
In the hope of aiding review this is broken up into three patches.
* [PATCH 1/3] flow_offload: add support for packet-per-second policing
Add support for this feature to the flow_offload API that is used to allow
programming flows, including TC rules and their actions, into hardware.
* [PATCH 2/3] flow_offload: reject configuration of packet-per-second policing in offload drivers
Teach all exiting users of the flow_offload API that allow offload of
policer action instances to reject offload if packet-per-second rate
limiting is configured: none support it at this time
* [PATCH 3/3] net/sched: act_police: add support for packet-per-second policing
With the above ground-work in place add the new feature to the TC policer
action itself
With the above in place the feature may be used.
As follow-ups we plan to provide:
* Corresponding updates to iproute2
* Corresponding self tests (which depend on the iproute2 changes)
* Hardware offload support for the NFP driver
Key changes since v2:
* Added patches 1 and 2, which makes adding patch 3 safe for existing
hardware offload of the policer action
* Re-worked patch 3 so that a TC policer action instance may be configured
for packet-per-second or byte-per-second rate limiting, but not both.
* Corrected kdoc usage
