I'm usually against separate "mobile versions" of websites but wow, this needs one.
Wow that's a tl;dr for me. Not only because of the length, also because of format. Not very readable on a smartphone...

This is so weird to me. It's not an interoperable standard. It isn't even interoperable on Linux, the one OS where it's popular.
There is an explanation here: https://lwn.net/ml/all/20241105035101.GD41004@maniforge/
Right, for offload, but XDP programs also depend on helper definitions, which themselves have not been consistent between versions of the Linux kernel.
I mean, there really is working XDP offload (Netronome, right?) so it can be made to work, but this spec doesn't define the hardest part of interoperability.
If you wanted it to become an interoperable standard, that's the obvious step, right?
