Subject: [PATCH 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".

Lukasz Majewski (4):
  net: dsa: Extend the dsa_switch 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
