We are currently accepting bug fixes only. Please repost when net-next reopens after Sept 11th. RFC patches sent for review only are obviously welcome at any time.

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 drivers/net/dsa/microchip/ksz9477.c | 96 ++++++++++++++++++++++++++ drivers/net/dsa/microchip/ksz9477.h | 4 ++ drivers/net/dsa/microchip/ksz_common.c | 81 ++++++++++++++++++++++ drivers/net/dsa/microchip/ksz_common.h | 3 + include/linux/dsa/ksz_common.h | 1 + net/dsa/tag_ksz.c | 5 ++ 6 files changed, 190 insertions(+)
