Subject: Cloudflare L4LB - UNIMOG - using XDP and TC cls

Hello,

I know the community is looking for examples of eBPF usage. David from
Cloudflare wrote a blog post about our Layer 4 Load Balancer called
UNIMOG. It's a long read but goes into many architectural details:

We added the tc cls component to the selftests:

Cheers,
