You do realise that phylink knows what speeds each interface supports
(see phylink_get_capabilities()) and restricts the media advertisement
to ensure that ethtool link modes that can't be supported by the MAC
capabilities and set of interfaces that would be used are not
advertised.

This should mean none of your verification ever triggers. If it does,
then I'd like to know about it.
