There is a fair bit of context behind this work. Some pointers:

1) Introduction. Receiving / sending packets with high throughput is hard:

2) Achieving low latency is also hard, quick intro to kernel bypass proprietary solution OpenOnload:

3) Oh, you want to do kernel bypass in open source? All of off-the-shelve open source solutions take over the whole network card.

4) Proposal for solving the problem in open source: the partial kernel bypass patch proposal to netmap:

5) It's there! The (updated) patch had been merged!

Great summation, although I read all of it before I had to recap. It's great that Cloudflare is open sourcing their work on the bypass network kernel space and we can be assured about how it holds in in production since they have the platform to battle test on.

That should be off-the-shelf. There's only the 'e' and voiced 'v' in the plural. "Shelve" does exist, but it's a verb, not the singular of "shelves".
