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: 5a1b322cb0b7d0d33a2d13462294dc0f46911172

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

Thanks!  

I hope, that it will find its way to net-next soon :-).

I'm a bit puzzled with this patch series - will it be pulled directly
to net-next [1] or is there any other (KSZ maintainer's?) tree to which
it will be first pulled and then PR will be send to net-next?

Thanks in advance for the clarification.

Thanks for your help and patience.
