Subject: [PATCH v2 0/4] 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
ifconfig lan1 up;ifconfig lan2 up
ifconfig hsr0 192.168.0.1 up
To remove HSR network device:
ip link del hsr0
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
Lukasz Majewski (4):
net: dsa: Extend the ksz_device structure to hold info about HSR ports
net: dsa: Extend ksz9477 TAG setup to support HSR frames duplication
net: dsa: hsr: Enable in KSZ9477 switch HW HSR offloading
net: dsa: hsr: Provide generic HSR ksz_hsr_{join|leave} functions
