Jakub Kicinski says: =================== net: act_police offload support this set starts by converting cls_matchall to the new flow offload infrastructure. It so happens that all drivers implementing cls_matchall offload today also offload cls_flower, so its a little easier for them to handle the actions in unified flow_rule format, even though in cls_matchall there is no flow to speak of. If a driver ever appears which would prefer the old, direct access to TC exts, we can add the pointer in the offload structure back and support both. Next the act_police is added to actions supported by flow offload API. NFP support for act_police offload is added as the final step. The flower firmware is configured to perform TX rate limiting in a way which matches act_police's behaviour. It does not use DMA.IN back pressure, and instead drops packets after they had been already DMAed into the NIC. IOW it uses our standard traffic policing implementation, future patches will extend it to other ports and traffic directions. =================== Signed-off-by: David S.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
