[00/11] MediaTek SoC flow offload improvements + wireless support

Message

Felix Fietkau Feb. 25, 2022, 10:17 a.m. UTC

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
