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
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: v6.5-rc7 Linux repository 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
