User-mode Forwarding Plan

[475683702]

Dear Team,

As far as I know, OpenWrt currently relies primarily on the Kernel's protocol stack for packet processing and forwarding. However, as some scenarios and requirements evolve (such as packet analysis, classification, and shaping), user-space packet processing technologies have become crucial.

I would like to know if the OpenWrt community has any plans to integrate user-space forwarding technology into the system. For example:
1. Are there plans to support DPDK or other similar user-mode network stacks?
2. If not at present, what is the community’s perspective on such technologies?
3. Does the community have any recommended paths or best practices for implementing user-mode forwarding on OpenWrt devices?

Looking forward to your response—this is very important for my project planning.

Thank you!
