Lowest-latency Ethernet: Byte-oriented NICs? (deleted from StackOverflow...)

Back in 2017 I had a kinda esoteric question about Ethernet NICs with less-than-frame latency, based on my experience with networking software and hardware, and the evidence for something "atypical" being in use by High Frequency Traders. So I posted my question to Stack Overflow. The question got a lot of pushback, which I found bizarre. It had to be moved across 3 SO sites... and finally it stayed in SO proper, where anyway the only response I got was my own, when some days later I found the necessary information myself. Aaand a couple of years of inactivity later, the question just got deleted. 🤷‍♂️ I thought it was an interesting question (else I wouldn't post it!); it was an interesting collection of pushback; and an interesting answer. So I saved them and here they are for posterity.
