On: RFC 9293: Transmission Control Protocol (TCP)

[pclmulqdq]

This is a really big help to anyone trying to implement TCP. At one previous job, we had to wade through ~20 RFCs to figure out how to write a hardware TCP system, paying particular attention to which RFC supersedes which sections of other RFCs. Consolidating to one RFC without the crazy dependency chain is a big improvement!

How did you test for compliance?

[pclmulqdq → amelius]

With great difficulty and a lot of different hardware on the other side of the link. We didn't need a fully standards-compliant implementation, though, so we cut a lot of corners.

[jdougan → pclmulqdq]

To be fair, that is pretty much the story of early interop testing: the bake-offs, where they put everyone in a room and tested against each other.
