[PATCH v2 00/14] MediaTek SoC flow offload improvements + wireless support

2022-04-05T19:59:16Z

This series contains the following improvements to mediatek ethernet flow
offload support:

- support dma-coherent on ethernet to improve performance
- add ipv6 offload support
- rework hardware flow table entry handling to improve dealing with hash
collisions and competing flows
- support creating offload entries from user space
- support creating offload entries with just source/destination mac address,
vlan and output device information
- add driver changes for supporting the Wireless Ethernet Dispatch core,
which can be used to offload flows from ethernet to MT7915 PCIe WLAN
devices

Changes in v2:
- add missing dt-bindings patches

David Bentham (1):
net: ethernet: mtk_eth_soc: add ipv6 flow offload support

Felix Fietkau (10):
net: ethernet: mtk_eth_soc: add support for coherent DMA
arm64: dts: mediatek: mt7622: add support for coherent DMA
net: ethernet: mtk_eth_soc: add support for Wireless Ethernet Dispatch
(WED)
net: ethernet: mtk_eth_soc: implement flow offloading to WED devices
arm64: dts: mediatek: mt7622: introduce nodes for Wireless Ethernet
Dispatch
net: ethernet: mtk_eth_soc: support TC_SETUP_BLOCK for PPE offload
net: ethernet: mtk_eth_soc: allocate struct mtk_ppe separately
net: ethernet: mtk_eth_soc: rework hardware flow table management
net: ethernet: mtk_eth_soc: remove bridge flow offload type entry
support
net: ethernet: mtk_eth_soc: support creating mac address based offload
entries

Lorenzo Bianconi (3):
dt-bindings: net: mediatek: add optional properties for the SoC
ethernet core
dt-bindings: arm: mediatek: document WED binding for MT7622
dt-bindings: arm: mediatek: document the pcie mirror node on MT7622
