Lorenzo Bianconi df8398fb7b net: airoha: Add matchall filter offload support
Introduce tc matchall filter offload support in airoha_eth driver.
Matchall hw filter is used to implement hw rate policing via tc action
police:

$tc qdisc add dev eth0 handle ffff: ingress
$tc filter add dev eth0 parent ffff: matchall action police \
 rate 100mbit burst 1000k drop

The current implementation supports just drop/accept as exceed/notexceed
actions. Moreover, rate and burst are the only supported configuration
parameters.

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 reStructuredText 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.
