Merge branch 'net-dsa-hsr-enable-hsr-hw-offloading-for-ksz9477'

====================
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: 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
