Implement the ethtool function to support users to obtain network card
information, including obtaining various device settings, Report whether
physical link is up, Report pause parameters, Set pause parameters,
Return a set of strings that describe the requested objects, Get number
of strings that @get_strings will write, Return extended statistics
about the device.

What are you reporting here? Does this refer to the link between MAC and
switch CPU port? Because I would assume that the switch ports can do autoneg.

PATCH 1/13 has our CHIP architecture. The mac and switch are directly connected, and the line seed is fixed at 5G, so there is no need for autoneg.
