By chipset, you mean northbridge? Or the CPU? The part I know of that is built into the CPU is a DMA engine called I/OAT; it just does DMA and maybe basic checksum and RAID transformations. It is sometimes confused with QAT (I've personally confused the two...): https://www.intel.com/content/www/us/en/wireless-network/acc...

The northbridge. my understanding is that they no longer sell the discrete cards to perform these tasks, and instead offload it to chips that come on the boards.

Isn't it great that we work in an industry where a company like Netflix, which has increasing competition lately, just shares potential competitive advantages like this? I get that, in part, this is a way to get people excited to work for Netflix, however, the people working on this are, probably, pretty proud of what they achieved and thus like to share it with us, their colleagues at other places of work and they h…

Not all of them are landed in CURRENT yet, much less stable/12. They'll be in 13.0; I can't speak to any future stable 12.2. On the other hand, CURRENT is pretty solid. A lot of folks, Netflix included, just run CURRENT.

Wait, they run CURRENT in production? Is that... safe?

It's funny to think that pushing 196gbps is possibly just as little as ~8000 simultaneous streams. Also a shame that it is TLS'd. The content already has its own DRM/encryption.

TLS plays a different role. It makes sure you're receiving the Netflix's DRMed and encrypted content, and not some MITMed content that also happens to be correctly DRMed and encrypted, but contains something else.
