Paolo Abeni 1412e667ef Merge branch 'net-dsa-hsr-enable-hsr-hw-offloading-for-ksz9477' 
Lukasz Majewski says:

====================
net: dsa: hsr: Enable HSR HW offloading for KSZ9477

This patch series provides support for HSR HW offloading in KSZ9477
switch IC.

To test this feature:
ip link add name hsr0 type hsr slave1 lan1 slave2 lan2 supervision 45 version 1
ip link set dev lan1 up
ip link set dev lan2 up
ip a add 192.168.0.1/24 dev hsr0
ip link set dev hsr0 up

To remove HSR network device:
ip link del hsr0

To test if one can adjust MAC address:
ip link set lan2 address 00:01:02:AA:BB:CC

It is also possible to create another HSR interface, but it will
only support HSR is software - e.g.
ip link add name hsr1 type hsr slave1 lan3 slave2 lan4 supervision 45 version 1

Test HW:
Two KSZ9477-EVB boards with HSR ports set to "Port1" and "Port2".

Performance SW used:
nuttcp -S --nofork
nuttcp -vv -T 60 -r 192.168.0.2
nuttcp -vv -T 60 -t 192.168.0.2

Code: v6.6.0-rc2+ Linux net-next repository
SHA1: 5a1b322cb0

Tested HSR v0 and v1
Results:
With KSZ9477 offloading support added: RX: 100 Mbps TX: 98 Mbps
With no offloading 		       RX: 63 Mbps  TX: 63 Mbps

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.
