For the record, "API not working" is not exclusively about mediaopt
settings.  "API not working" also kills SFP DOM stats, something which
is quite useful when troubleshooting with third-parties on the other
side of your fibre link.

When someone on the other side of the phone asks for "light levels",
its rather nice to be able to give them an answer .... ;-)

Yeah, I understand. That is why my first e-mail only recommended a
copper-based solution if one insists on using the most recent firmware.
Then upon learning that autonegotiation is only a thing for Ethernet
over twisted pair, I revised the recommendation more conservatively to
only include SFP+ DAC solutions since I would not be surprised if X710
does not work on the most recent firmware for something like the
X710-T4L network interface adapter.

With something like the X710-DA2-more relevantly for the OP, the
X710-DA4-it definitely works, and "light levels" are obviously not a
thing. As a result, one might be able to get 10 Gbps if one is willing
to use a different controller (e.g., X520), use an older firmware for
X710, or use an X710 SFP+ DAC adapter in addition to using "amd fast,
not intel fast" CPU cores.

Of course as mentioned and likely known, SFP+ DAC may not be a
possibility if EMI is an issue, the runs are very long, or fiber is
forced upon you by the other end. If not though; then enjoy the cheaper,
equally performant, and less power hungry passive SFP+ DAC solution.
