Packets that are trapped via tc's trap action are currently subject to the same policer as packets hitting local routes. The latter are critical to the correct functioning of the control plane, while the former are mainly used for traffic inspection. Split the ACL trap to a separate group with its own policer. Use a higher priority for these traps than for traps using mirror action (e.g., ARP, IGMP). Otherwise, packets matching both traps will not be forwarded in hardware (because of trap action) and also not forwarded in software because they will be marked with 'offload_fwd_mark'.

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.
